In the year 2000, America was sharply divided. A new generation of singers had lip-synced and danced its way to the top of the charts and the front of the pop culture proscenium with material Auto-Tuned to Pro Tools perfection. The (mostly rock) music establishment loudly decried the new pop as artifice and asserted the integrity of music made with analog instruments.

At the time, assessing the validity of popular music loomed larger than the growing threat of MP3 downloads that would eventually upend the entire record industry. Madonna had been through these kinds of polemics before, herself a frequent subject of musical legitimacy debates. But nearly two decades into her career, she had seemed to quiet her most ardent critics. 

Her seventh studio album, 1998's Ray of Light, had been the best-reviewed record of her career thus far, earning five GRAMMY nominations and winning three, including Best Pop Album, in 1999. Along with a pair of soundtrack singles, the album had maintained Madonna's presence on radio into the summer of 2000. On MTV's "Total Request Live," her videos played between those from upstart stars half her age, many of whom would cite her as an inspiration. In a contentious cultural landscape, Madonna occupied the highly coveted overlapping space of critical credibility and popular viability. 

Ray of Light struck gold by embracing Björk- and Massive Attack-esque electronica, thanks largely to the work of the album's primary producer, William Orbit. However, as a genre, electronica had yet to live up to predictions that it would dominate the U.S. as it had Europe. In combination with Madonna's reputation for reinvention, this only drove expectations higher for how she would follow her latest career highpoint.

"Music," the lead single and title track of her eighth studio album, struck the airwaves like an intergalactic robot in August 2000, heralding a new sound for Madonna and the arrival of 21st-century pop music. With its digitally modified instruments, arpeggiated synths and a chorus Madonna says was inspired by the crowd at a Sting concert, "Music" combined elements of electronic and analog to create an anthem of unity on the dance floor. The Jonas Åkerlund-directed music video—featuring a pre-Borat Sacha Baron Cohen as his character, Ali G—seemed to skewer the decadence of late-'90s hip-hop bling while also revelling in it. We see a pimp-suited Madonna getting into the groove, relishing a night at the strip club with her girls and fending off creeps like a boss, all filmed while she was five and a half months pregnant.

On the strength of its lead single, Music released in the U.S. on September 19, 2000, via Madonna's Maverick imprint under Warner Bros. and opened at No. 1 on the Billboard 200, her highest-charting album in over a decade. Although critics didn't gush over Music with quite the same enthusiasm as they had its predecessor, the album moved millions of physical copies in its first few weeks, eventually going on to garner triple-platinum certification in the U.S. It ultimately earned five total GRAMMY nominations, including Best Pop Vocal Album and Record Of The Year for "Music" in 2001 and Best Short Form Music Video for "Don't Tell Me" in 2002. (Former Maverick Records art director and designer Kevin Reagan, who designed the album, won for Best Recording Package in 2001.)

In an effort to introduce the Queen of Pop to a new generation of fans, the album's promo campaign combined the traditional (a terrestrial radio premiere, a Rolling Stone cover story) with the new (an AOL listening party/live chat, a livestreamed club performance) over a timeline that seems enviably long by today's standards. Comparisons to more junior pop artists on the charts and airwaves swirled around her, but Madonna avoided miring herself in the muck. 

Instead, for an exclusive performance at New York City's 3000-capacity Roseland Ballroom that November, Madonna took the stage wearing a Dolce & Gabbana-designed T-shirt emblazoned with the name Britney Spears. For her performance at MTV's European Music Awards later that month, she wore a similar shirt that said Kylie Minogue. "It's my celebration of other girls in pop music," she said backstage at the EMAs, praising the younger women before adding, somewhat cheekily, "I think they're the cutest."

Such spontaneous statements of support and admiration are almost boringly common now, but in an era when pop music had been denied entry into the credibility club, the moment held more weight. Though the press loved to pit female pop stars against each other at the turn of the century as much as it does now, musically, there wasn't much rivalry between them. With Spears still steeped in the sounds of Swedish pop on Oops!… I Did It Again and Minogue diving into disco on Light Years, Madonna had crafted a sound of her own on Music. 

While Orbit returned for several tracks on the album, the majority of Music was co-helmed by the relatively unknown French producer Mirwais Ahmadzaï. Like his contemporaries in the French touch electronic scene (Daft Punk, Air, Rinôçérôse), Mirwais was unabashed in his affection for American music of the '70s, including the funk and R&B influences of house. Those influences, paired with his proficiency in production, worked well with Madonna's penchant for pop hooks, resulting in an LP whose sonic textures included space-age fills, guitar-washed in computerizing effects, and vocals that alternate between alien and intimate. 

Music's second track, the distorted and ravey fan favorite "Impressive Instant," is a high-BPM ode to a trippy first encounter that sounded then like nothing anyone had heard before—20 years later, it still does. On the opposite end of the spectrum, closing track "Gone" is a stark and straightforward crooner made glorious by the fortitude of Madonna's vocals, selectively layered with exacting control. 

<style>.embed-container { position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden; max-width: 100%; } .embed-container iframe, .embed-container object, .embed-container embed { position: absolute; top: 0; left: 0; width: 100%; height: 100%; }</style><div class='embed-container'><iframe src='https://www.youtube.com/embed/gLFWRDsx5AI' frameborder='0' allowfullscreen></iframe></div>

As an album, Music is a masterclass in juxtaposition that disguises some of its strangest elements in familiarity. Where futuristic production might distract, it's moderated by traditional instrumentation. This plays out most noticeably on second single, "Don't Tell Me." It's hard to hear the track's opening guitar riff without thinking of the album's disco cowboy visual aesthetic come to life in the Jean-Baptiste Mondino-directed video. The record soundtracking the sparkly western shirts and synchronized line dancing is downright audacious in how it interweaves acoustic guitar—played by Madonna herself—with midtempo dance beats, cushioned by country strings, all building to a crescendo in the final chorus. "Don't Tell Me" so effortlessly realizes the misbegotten '90s vision of folktronica that it sounds just as fresh today as it did in 2000. 

As a mainstay of '90s soft rock radio, Madonna was no stranger to love songs. Given the magnitude of her celebrity, the details of her personal life were bound to color how listeners heard Music's more personal lyrics. Two decades later, the declarations of love on "I Deserve It," presumably intended for then-boyfriend, husband-to-be Guy Ritchie, feel just as authentic now, long after their relationship ended. In contrast to the frequent unironic materialism expressed by today's celebrity pop stars, Music excelled at showing the former "Material Girl" in self-reflection. Its genius is how that introspection comes across as relatable and real, even when sung to highly synthesized beats by one of the biggest stars in the world.

For all its ebullience, at only 10 tracks and clocking in just under 45 minutes, Music is a model of restraint. It's the work of an artist who has plenty to say, but nothing to prove. And while her status as an innovator is deserved, Music shows how Madonna is an even better interpreter, fluent in musical languages across genres and capable of hewing them to her vision. 

Although Music faces forward to the new century, its unencumbered joyfulness is a bittersweet vestige of the uncomplicated '90s. When she wielded her axe on stage for the kickoff of the Drowned World Tour in June 2001, it was a subtle statement of sorts, expressing Madonna's own defiance of music rules: She could be both rock and pop, analog and digital, acoustic and electronic. But by the time that tour wrapped in Los Angeles on September 15, 2001, nobody cared about that debate anymore.

While she had deftly eschewed the petty cultural battles between genres and generations, the world had changed dramatically in the first year since the release of Music. The message would be muddled in years to come, but in that moment, Madonna was uniquely prepared to be a voice for unity with one simple yet inarguable statement: Music makes the people come together.

Dua Lipa Talks 'Club Future Nostalgia,' Working With Madonna And How She's Navigating The Music Industry In The COVID-19 Era

As someone who has dedicated her life to being a performer, Dua Lipa's recent admission to Apple Music's Zane Lowe seems almost unfathomable: "I never thought of the idea of being famous."

Stardom may not have been on her mind as a kid, but Lipa is now, indeed, one of the most famous pop stars on the planet as she releases her highly anticipated third album, Radical Optimism. 

In the seven years since her acclaimed 2017 self-titled debut, Lipa has achieved several highs — like three GRAMMY wins, including Best New Artist in 2019 — as well as the subsequent lows that can often come with global stardom. And though the singer also admitted to Lowe that it "took me a while to find my voice," Radical Optimism is her most self-assured album yet — one that hinges on the title being not only the project's name, but also its defining approach to Lipa's present-day vision for her life.

"Radical Optimism and the way that I see it is this idea of rolling with the punches, of not letting anything get you down for too long. Of always seeing the positive side of things. Of being able to grow and move forward and change your perspective regardless of what's happening in your life…I think it's a big part of maturing and growing up."

The entire album was crafted in her native London over the course of a year-and-a-half, with Lipa enlisting a small band of collaborators — including her righthand co-writer Caroline Ailin, Kevin Parker of Tame Impala, Danny L. Harle and Tobias Jesso, Jr. — to create a cohesive, buoyant body of work tinged with disco, funk and bits of psychedelic pop.

Naturally, "radical optimism" is a core thread that runs through all eleven songs as Lipa reflects on falling in and out of love, grapples with her fame and confidently declares that everything that came before Radical Optimism was just a practice run. After all, as she brazenly declares on the LP's second single, "Training season's over." 

As you enter Dua's latest musical world, dive into four major takeaways from Radical Optimism below.

Radical Optimism Isn't Just A New Era — It's A Whole New Perspective

When Lipa accepted her GRAMMY for Best Pop Vocal Album in 2021, she declared she was officially done with the "sad music" that had fueled her breakout debut album. And if 2020's Future Nostalgia was, in context, a kind of clubby, '80s-driven turning point for the artist, she fully embraces the Radical Optimism promised by its follow-up's title. Lipa's newfound attitude is both clear-eyed and relentlessly positive across the album's 11 tracks, whether she's gushing over a new love on giddy opener "End of an Era," being kept up all night by thoughts of a seductive crush on "Whatcha Doing" or cutting her losses and ditching out early on the spellbinding "French Exit."

Even "These Walls," on which she watches a doomed relationship fade to black, is approached with a sense of inevitability laced with clarity and astute kindness. "But if these walls could talk/ They'd say enough, they'd say give up/ If these walls could talk/ They'd say/ You know you're f—ed/ It's not supposed to hurt this much/ Oh, if these walls could talk/ They tell us to break up," Lipa sings over gossamer production and a piano line by Andrew Wyatt.

You Can Still Find Her On The Dance Floor

The rollout for Radical Optimism was front-loaded with the release of three singles ahead of the full album in the form of "Houdini," "Training Season" and "Illusion." Between the three subsequent music videos and a thrilling live performance at the 2024 GRAMMYs in February, Lipa signaled that her third LP would be filled with her signature style of scintillating dance floor bangers.

The rest of the album more than delivers on that promise, with an overall BPM that rarely falls below what's needed for a full-blown aerobic workout — perfect for over-the-top choreography, of course. And in case the Service95 founder's commitment to the dance floor isn't already apparent, just look at the history-making hat trick she recently pulled off on the Billboard's Hot Dance/Electronic Songs chart: as of press time, "Houdini," "Illusion" and "Training Season" occupied the top three spots, marking a first for any female artist in modern music history.

She's Redefining Love On Her Own Terms

If the litany of love songs on Radical Optimism are any indication, it's safe to say Lipa is head over heels these days (with boyfriend Callum Turner, perhaps?). Opening track "End of an Era" may mark the beginning of a new musical journey for the singer, but it's just as much about the thrill of a new relationship. Later on the track list, she uses album cut "Falling Forever" to grow an initial spark of infatuation into a red-hot love affair as she yearns, "How long, how long/ Can it just keep getting better?/ Can we keep falling forever" on the lovestruck chorus.

Lipa also makes it clear on the shapeshifting highlight "Anything For Love" that she's "not interested in a love that gives up so easily." As she refuses to accept the modern paradigm of ghosting, non-committal situationships and running away when things get hard, the song morphs from a tender piano ballad into danceable, mid-tempo groove, giving the listener just enough breathing room to wrestle with the questions of what kind of love they'll accept before dancing it out.

She's Putting Her Emotional Growth On Full Display

It's been almost seven years since Lipa spelled out her "New Rules" for a generation of pop lovers, and some of the most affecting cuts on Radical Optimism prove the British-Albanian star has accrued even more hard-won wisdom since her early days of "If you're under him, you ain't gettin' over him."

Penultimate track "Maria" finds Lipa thanking the ghost of her current lover's ex-girlfriend for making him a better man: "Never thought I could feel this way/ Grateful for all the love you gave/ Here's to the lovers that make you change/ Maria, Maria, Maria." 

Meanwhile, on album closer "Happy for You," the singer turns her attention not to a lover's ex-girlfriend, but to an ex who's moved on from her and found himself happier than ever. It's a complex, but decidedly mature feeling to realize you're genuinely happy for someone you used to love, but Lipa encapsulates the emotion perfectly. 

"Oh, I must've loved you more than I ever knew/ Didn't know I could ever feel/ 'Cause I'm happy for you," she sings on the chorus. "Now I know everything was real/ I'm not mad, I'm not hurt/ You got everything you deserve/ Oh, I must've loved you more than I ever knew/ I'm happy for you."

The grown-up sentiment finishes the album on a bittersweet emotional high — proving that no matter what life throws at her, Lipa will remain radically and unapologetically optimistic to the end. 

GRAMMY Rewind: Dua Lipa Champions Happiness As She Accepts Her GRAMMY For Best Pop Vocal Album In 2021

Long before Dua Lipa reached pop megastardom, she declared the mantra that would soon become the core of her art: "It has to be fun."

Whether in club-hopping evenings or tear-streaked mornings, Lipa has continuously found a way to bring catharsis and movement into every moment — and, subsequently, every song she's released. So when she announced that her new album would be called Radical Optimism, the second word seemed obvious. But what would radical mean for Dua Lipa, and how did she get there?

Considering her time as a model prior to her music career taking off, many found it easy to write off the London-born singer as by-the-books pop, all-image artist. But even before taking a listen to her self-titled debut, Lipa's upbringing reveals far more complex feelings and inspirations.

The daughter of Kosovo Albanian parents living in London, Lipa took notes from her musician father, digging deep on the likes of the Police, David Bowie and Radiohead, while dancing to Ciara and Missy Elliott with her classmates. After a four-year stint in Kosovo when her family relocated, the then 15-year-old Dua moved back to London to stay with a family friend and build towards an inevitable music-oriented life, which began with clubbing incessantly and posting covers of Alicia Keys and Christina Aguilera on YouTube.

Lipa was still working in restaurants when she first made contact with the music industry, burning the candle at both ends — as well as a third end unseen to mortals. "I'd finish work, then go out to whatever nightclub was happening until, like, 3 in the morning," she recently recalled to Elle. "Then I would wake up and go to the studio until I had my shift again at, like, 8 pm."

Warner Bros. Records caught wind of those sessions and signed her in 2014, leading to even more time in the studio (and, likely, less waitressing). Her debut single, 2015's "New Love," showcases everything that would lead to her eventual pop takeover: the resonant, sultry vocals, a propulsive beat, and a video full of effortless cool.

There would be seven more singles to follow from 2017's Dua Lipa, with the budding pop star co-writing a majority of the albums' tracks, alt R&B icon Miguel collaborating on a song, and Coldplay's Chris Martin providing additional vocals on the closer. While there are plenty of hits to take away ("Blow Your Mind (Mwah)" is a particular favorite in its grand and stompy disco sass), the true star here is "New Rules." Detailing the "rules" to avoid a problematic ex, the song could be cloying and twee, but Lipa's chill swagger sells the dance floor intensity and female empowerment in equal doses.

Listeners around the world agreed, as the song marked Lipa's first No. 1 in the UK and several other countries, as well as her first top 10 hit in the U.S. It also earned Lipa spots at festivals, a performance on Later… With Jools Holland, and five nominations at the 2018 Brit Awards — the most of any artist that year. She laid out a pretty clear manifesto after winning British Female Solo Artist: "Here's to more women on these stages, more women winning awards, and more women taking over the world."

As that year went on, Lipa solidified her own role in that mission. She became a hot collaboration commodity, first linking with Calvin Harris for the UK chart-topping "One Kiss"; then teaming with Mark Ronson and Diplo's Silk City for another club hit, "Electricity"; and even being recruited for Andrea Bocelli for "If Only," a track on his 2018 album, Sì. Her breakthrough was cemented in GRAMMY gold at the 2019 ceremony, too, as she won two golden gramophones: Best Dance Recording for "Electricity," and the coveted Best New Artist.

Early word of the Dua Lipa followup, Future Nostalgia, was that Lipa was amping the disco energy. "[The album] feels like a dancercise class," she hinted in July 2019 to the BBC, who also reported that the now full-fledged pop star was working with Pharrell, Nile Rodgers, Tove Lo, and Diplo.

Lead single "Don't Start Now" was co-written with the team behind "New Rules," and the hyper-elastic bass, MIDI strings, and honest-to-goodness cowbell more than lived up to her promise of disco domination. The track went platinum in five countries, a feat that would go on to be topped by multiple tracks on the album, including the smoldering "Physical" and the INXS-interpolating "Break My Heart."

The album's March 2020 release was a thing of anxious beauty. It could've been pure tragedy to release an album designed for sweaty, crowded clubs in the throes of the COVID-19 pandemic. And when the album leaked a full two weeks prior to its release, even Lipa wasn't sure if her timing was right. "I'm not sure if I'm even doing the right thing, but I think the thing we need the most at the moment is music, and we need joy and we need to be trying to see the light," she said in an Instagram Live days before the album's release.

True to that spirit, Lipa's openhearted enthusiasm and unadulterated fun made the album a staple of lockdown dance parties and wistful dancefloor daydreams. In a bit of chicken-and-egg magic, the album's runaway hit is the inescapable "Levitating." The song's buoyant synth pulse, clap-along disco groove, drippy strings and punchy hook add to something far greater than the sum of its parts. And DaBaby's in-the-cut remix verse helps fulfill Lipa's rap-meets-pop dreams. But it definitely didn't hurt to have the track basically overrun TikTok — and a video produced in partnership with the platform — at a time when we were all stuck at home, looking at our phones as a way to connect with the world.

That was only the beginning of the pop star's effort to make the most of the pandemic era; Lipa continued to find innovative ways to bring fans into her disco-fueled sonic universe for some joy and connection. For one, she evolved Future Nostalgia into a remix album: Club Future Nostalgia, featuring electronic minds like Moodymann and Yaeji, as well as high-profile guests like BLACKPINK, Madonna, and Missy Elliott. And while fans who had grown connected to the album were hungry for an event to attend, she developed Studio 2054. The technicolor, gleeful live-streamed event saw millions of viewers virtually join Lipa in an immaculately choreographed, star-studded dance party — one that further displayed her magnetic personality and in-the-moment attitude.

Through the entire Future Nostalgia era, Lipa's purpose further proved to be more than the music. Yet again, it was about the amount of fun and energy it was able to provide to fans, something that proved to resonate in an even bigger way than her first project.

"[Future Nostalgia] took on its own life. And that in itself showed me that everything is in its own way for its own specific purpose, for its own reason," she told Variety earlier this year. "As long as I'm being of service and the music is there and it's a soundtrack for a moment in time, or in someone's life, then I've done what I was supposed to do."

Before getting to work on her third LP, Lipa kept the dance party going with new and old collaborators. First, she scored another UK No. 1 and U.S. top 10 hit alongside Elton John with "Cold Heart (Pnau remix)"; later, she was enlisted for feel-good singles from Megan Thee Stallion and Calvin Harris' 2022 albums. Then, a reunion with Mark Ronson led to a summer 2023 detour in Barbie land, resulting in another disco-tinged smash, "Dance the Night," for the blockbuster film's soundtrack (as well as her acting debut!).

With the good vibes clearly not fading, Lipa was primed for her next musical venture. In November, she unveiled the lead single to her next project, "Houdini," a swirling track that features a trio of new collaborators — and a brilliant, if seemingly dissimilar, set of co-writers at that: former PC Music electronic experimentalist Danny Harle, Tame Impala frontman (and retro psychedelia mastermind) Kevin Parker, and breezy Canadian singer/songwriter Tobias Jesso Jr. But with her trusty songwriter pal Caroline Ailin also in tow, Lipa retained the same trademark dance pop pulse amid crunchy bass and stomping percussion — putting the Radical into the Optimism.

She kept the same team (and energy) for the album's subsequent singles, "Training Season" and "Illusion." The former thumps and jitters underneath Lipa opting for a willowy falsetto in the chorus, a song that can unite Tame Impala psych addicts and more traditional poptimists at the club. And where earlier Lipa tracks might have been more eager to get to a bright punch, "Illusion" smolders patiently, trusting that the vocalist's charisma can buoy even the subtler moments.

While the album's first three singles carry echoes of the propulsive, dance floor energy of Future Nostalgia, Lipa took more notes from a more modern pop era than the disco days on Radical Optimism. "I think the Britpop element that really came to me was the influences of Oasis and Massive Attack and Portishead and Primal Scream, and the freedom and the energy those records had," she told Variety. "I love the experimentation behind it."

But, she insists, that's not to say that she's produced the next "Wonderwall." This isn't Dua Lipa's Britpop turn, but rather her latest experiment in finding freedom and embracing the moment.

"When I hear 'Teardrop' by Massive Attack and I'm like, 'how did this song even come to be? It feels like it just happened in a moment of real freedom and writing and emotion," she continued in the Variety interview. "And I think that was just the feeling I was trying to convey more than anything."

And in her mind, that freedom needs to remain at the core of everything — whether working through a global pandemic or working on a new project. "I think it's important that we just learn to walk through the fire and not hide away from it, or shy away from it," she added. "That's just optimism. It's probably the most daring thing we can do."

In her latest track "Off Switch," Australian dance-pop artist VASSY captures the exhilarating intensity of a budding romance. She loves the rush but, at the same time, wishes she could fight the feeling, even if only for a few seconds.

"There's something electric between you and I/ The way we connected I can't describe/ We're right on the edge of blurring the lines/ Don't know why I'm scared of this rush inside," she sings in the intro. "I wish my heart, it had an off switch/ 'Cause, boy, I don't know how to stop this."

In this episode of Global Spin, watch VASSY deliver an acoustic performance of her track, playing guitar and using a pair of castanets for added rhythm.

VASSY released "Off Switch" on Jan. 5 with an electrifying music video swirling with vibrant neon lights. 

Recently she wrapped a string of appearances supporting Aqua's United States leg of their world tour and earlier this month, performed a headlining show in San Diego. On May 18, she will take the stage at the BASSINTHEGRASS music festival in Darwin, Australia.

2024 GRAMMYs: Kylie Minogue Wins First-Ever GRAMMY For Best Pop Dance Recording For "Padam Padam"

"...and you're watching Disney Channel!" For anyone who grew up in the 2000s, those five words likely trigger some pretty vivid imagery: a glowing neon wand, an outline of Mickey Mouse's ears, and every Disney star from Hilary Duff to the Jonas Brothers. 

Nearly 20 years later, many of those child stars remain instantly recognizable — and often mononymous — to the millions of fans who grew up with them: Miley Cyrus, Selena Gomez and Demi Lovato. Nick, Kevin and Joe. 

Each of those names has equally memorable music attached to it — tunes that often wrap any given millennial in a blanket of nostalgia for a time that was, for better or for worse, "So Yesterday." And all of those hits, and the careers that go with them, have the same starting point in Hollywood Records, Disney Music Group's pop-oriented record label.

This time in Disney's history — the core of which can be traced from roughly 2003 to 2010 — was impactful on multiple fronts. With its music-oriented programming and multi-platform marketing strategies, the network launched a procession of teen idols whose music would come to define the soundtrack to millennials' lives, simultaneously breaking records with its Disney Channel Original Movies, TV shows and soundtracks.

Now, two decades later, Disney Music Group launched the Disney 2000s campaign, honoring the pivotal, star-making era that gave fans a generation of unforgettable pop music. The campaign will last through August and lead directly into D23 2024: The Ultimate Fan Event with special vinyl releases of landmark LPs and nostalgic social media activations occurring all summer long. April's campaign activation was Disney 2000s Weekend at the El Capitan Theatre in Hollywood, which featured special screenings of 2008's Hannah Montana & Miley Cyrus: Best of Both Worlds Concert and 2009's Hannah Montana: The Movie and Jonas Brothers: The 3D Concert Experience.

But before Miley and the JoBros, Hollywood Records' formula for creating relatable (and bankable) teen pop stars began with just one name: Hilary Duff. At the time, the bubbly blonde girl next door was essentially the face of the network thanks to her starring role in "Lizzie McGuire," and she'd just made the leap to the big screen in the summer of 2003 with The Lizzie McGuire Movie. In her years with Disney, Duff had dabbled in recording songs for Radio Disney, and even released a Christmas album under Buena Vista Records. However, her first album with Hollywood Records had the potential to catapult her from charming tween ingénue to bonafide teen pop star — and that's exactly what it did.

Released on August 26, 2003, Duff's Metamorphosis sold more than 200,000 copies in its first week and debuted at No. 2 on the Billboard 200. The following week, the bubblegum studio set performed the rare feat of rising from No. 2 to No. 1, making the then-16-year-old Duff the first solo artist under 18 to earn a No. 1 album since Britney Spears.

The album's immediate success was no fluke: Within a matter of months, Metamorphosis had sold 2.6 million copies. Music videos for its radio-friendly singles "So Yesterday" and "Come Clean" received constant airplay between programming on the Disney Channel. (The latter was eventually licensed as the theme song for MTV's pioneering teen reality series "Laguna Beach: The Real Orange County," giving it an additional boost as a cultural touchstone of the early '00s.) A 33-date North American tour soon followed, and Hollywood Records officially had a sensation on their hands. 

Naturally, the label went to work replicating Duff's recipe for success, and even looked outside the pool of Disney Channel stars to develop new talent. Another early signee was Jesse McCartney. With a soulful croon and blonde mop, the former Dream Street member notched the label another big win with his 2004 breakout hit "Beautiful Soul."

"When 'Beautiful Soul' became the label's first No. 1 hit at radio, I think that's when they really knew they had something," McCartney tells GRAMMY.com. "Miley [Cyrus] and the Jonas Brothers were signed shortly after that success and the rest is history.

"The thing that Disney really excelled at was using the synergy of the channel with promoting songs at pop," he continues. "I did appearances on 'Hannah Montana' and 'The Suite Life of Zack & Cody' and my music videos were pushed to Disney Channel. The marketing was incredibly brilliant and I don't think there has been anything as connected with an entire generation like that since then."

By 2006, Disney had nearly perfected its synergistic formula, continually launching wildly popular tentpole franchises like High School Musical and The Cheetah Girls, and then giving stars like Vanessa Hudgens and Corbin Bleu recording contracts of their own. (Curiously, the pair's HSM co-star Ashley Tisdale was never signed to Hollywood Records, instead releasing her first two solo albums with Warner.) 

Aly Michalka showed off her vocal chops as sunny girl next door Keely Teslow on "Phil of the Future," and fans could find her off-screen as one half of sibling duo Aly & AJ. In between their 2005 debut album Into the Rush and its electro-pop-charged follow-up, 2007's Insomniatic, Aly and her equally talented younger sister, AJ, also headlined their own Disney Channel Original Movie, Cow Belles. (Duff also helped trailblaze this strategy with her own early DCOM, the ever-charming Cadet Kelly, in 2002, while she was simultaneously starring in "Lizzie McGuire.")

Even after years of proven success, the next class of stars became Disney's biggest and brightest, with Miley Cyrus, Selena Gomez, Demi Lovato and the Jonas Brothers all joining the network — and record label — around the same time. "Hannah Montana" found Cyrus playing a spunky middle schooler by day and world-famous pop star by night, and the network leveraged the sitcom's conceit to give the Tennessee native (and daughter of '90s country heartthrob Billy Ray Cyrus) the best of both worlds. 

After establishing Hannah as a persona, the series' sophomore soundtrack introduced Miley as a pop star in her own right thanks to a clever double album that was one-half Hannah's music and one-half Miley's. It's literally there in the title: Hannah Montana 2: Meet Miley Cyrus.

From there, Cyrus' stardom took off like a rocket as she scored back-to-back No.1 albums and a parade of Top 10 hits like "See You Again," "7 Things," "The Climb," "Can't Be Tamed," and the ever-so-timeless anthem "Party in the U.S.A."

At the same time, Gomez had top billing on her own Disney Channel series, the magical (but less musical) "Wizards of Waverly Place." That hardly stopped her from launching her own music career, though, first by fronting Selena Gomez & the Scene from 2008 to 2012, then eventually going solo with the release of 2013's Stars Dance after the "Wizards" finale aired.

For her part, Lovato — Gomez's childhood bestie and "Barney & Friends" costar — got her big break playing Mitchie Torres in Camp Rock alongside the Jonas Brothers as fictional boy band Connect 3, led by Joe Jonas as the swaggering and floppy-haired Shane Gray. Much like Duff had five years prior in the wake of The Lizzie McGuire Movie, Lovato released her debut solo album, 2008's Don't Forget, just three months after her DCOM broke records for the Disney Channel. 

Building off their chemistry from the movie musical, nearly the entirety of Don't Forget was co-written with the Jonas Brothers, who released two of their own albums on Hollywood Records — 2007's Jonas Brothers and 2008's A Little Bit Longer — before getting their own short-lived, goofily meta Disney series, "Jonas," which wrapped weeks after the inevitable Camp Rock sequel arrived in September 2010.

As the 2000s gave way to the 2010s, the Disney machine began slowing down as its cavalcade of stars graduated to more grown-up acting roles, music and careers. But from Duff's Metamorphosis through Lovato's 2017 LP, Tell Me You Love Me, Hollywood Records caught lightning in a bottle again and again and again, giving millennials an entire generation of talent that has carried them through adulthood and into the 2020s.
