Before Spotify, before iTunes, before the industry knew how to handle digital, one Metallica song slipped out of its box and changed the way radio — and the world — thought about music leaks.
When Metallica’s single “I Disappear” suddenly hit the airwaves in spring 2000, the band hadn’t even released it yet. For fans flipping across the FM dial, it felt like they were getting away with something. A secret. A leak that wasn’t supposed to exist outside of studio walls. But for programmers and DJs, there was no mystery. The song had come straight from Napster, the new peer-to-peer file-sharing platform rewriting the rules of music distribution.
In the days before streaming, radio was still one of the primary ways fans heard new music first. Labels carefully controlled the rollout of singles, mailing out promo CDs and advance copies weeks before a song officially “went for adds.” This was how radio worked for decades: tightly managed, structured release calendars, and gatekeepers in both the label and the station. But Napster threw all of that out the window. Suddenly, millions of people had access to the same MP3s that only record executives once held — and some radio programmers saw no reason to wait for the official mailing list when their listeners were already passing the song around online.
Before Napster: how radio got its music
For decades, the music industry operated like a well-oiled supply chain. Record labels would press singles onto vinyl or CD and ship them out to stations in big padded envelopes marked For Promotional Use Only. Radio stations subscribed to record pools or maintained close relationships with local label reps who hand-delivered advance copies. That’s how programmers built playlists: through access and relationships.
It wasn’t fast, but it was predictable. By the time a listener heard a new single on their favorite station, a whole process had unfolded behind the scenes. That structure ensured that labels maintained control over when, where, and how new music reached the public. Radio was the amplifier, not the distributor.
But then came Napster.
Napster’s rise and the leak
Launched in June 1999 by Shawn Fanning, Napster was designed for one thing: music trading. In less than a year, the service ballooned to over 20 million users and was moving songs faster than the industry could comprehend. College dorm networks were saturated with MP3s, broadband connections were still rare, and yet Napster’s traffic kept climbing.
By spring 2000, Metallica’s new track “I Disappear” — recorded for the Mission: Impossible 2 soundtrack — showed up on Napster before its official release date. Within days, it was everywhere. Anyone with a dial-up connection could grab it. And that included radio stations.
Some programmers treated it like they had just been handed an exclusive. Why wait for the promo CD when the MP3 was right there? The track went into rotation at stations in Los Angeles, New York, and Chicago before Elektra Records had even hit “send” on their mailing list. For the first time, radio wasn’t following the industry’s calendar — it was following the internet’s.
Metallica fights back
Metallica didn’t see it as harmless fun. On April 13, 2000, the band sued Napster in federal court, claiming the service was enabling “wholesale theft” of their work. Drummer Lars Ulrich famously appeared before the Senate Judiciary Committee with a stack of papers listing over 335,000 users who had illegally shared Metallica tracks. He hand-delivered the names to Napster’s offices in a moment that instantly cemented the band as the face of the anti-file-sharing movement.
But here’s the irony: while Metallica was fighting Napster in court, their unreleased track was climbing radio charts thanks to the very service they were trying to shut down. Listeners weren’t waiting for labels anymore. They weren’t even waiting for radio. The MP3s were spreading whether anyone liked it or not.

The “Napster Bad” image comes from the series that was produced in the years 2000-2001 by Bob Cesca from a group then known as Camp Chaos, satirizing Metallica and their MP3 sharing crackdown.
Radio caught in the middle
For programmers, the leak created a moral gray zone. Playing “I Disappear” meant acknowledging that radio was now downstream from the internet. In an era when “world premiere” events were carefully staged with label sign-off, this was unprecedented.
Stations that jumped on the leak scored ratings points. Fans tuned in precisely because the track wasn’t supposed to be there. It felt rebellious, dangerous even, to hear it blasting through a car stereo before it was available at the record store. But not everyone in radio was comfortable with the move. Some programmers worried that leaning on pirated MP3s undermined their credibility with labels. Others saw it as simply reflecting reality: their listeners already had the song, and radio couldn’t afford to be slower than the audience.
This moment was pivotal. It forced stations to recognize that the internet wasn’t just competition; it was now a source. For decades, programmers had relied on being the tastemakers. Suddenly, they were scrambling to keep up with what fans were finding online.
The cultural shift
Looking back, the “I Disappear” leak wasn’t just a Metallica story. It was a turning point for music culture. Napster’s rise made it clear that digital distribution wasn’t just possible — it was inevitable. Within a few years, services like iTunes and later Spotify would legitimize what Napster had pioneered. The label’s tight grip on release schedules loosened, and radio learned that “first play” didn’t always belong to them anymore.
Metallica, meanwhile, bore the brunt of the backlash. Fans saw their lawsuit as an attack on the very community that had supported them. Memes, cartoons, and viral flash animations like “Napster Bad” mocked Ulrich’s crusade. While the band eventually mended its reputation, for a while they became symbols of the industry’s refusal to adapt.
The legacy on radio
The radio industry learned two big lessons from Napster. First: don’t underestimate the speed of digital sharing. Second: listeners will always chase the fastest, easiest path to new music — even if it means bypassing traditional channels.
In some ways, the episode foreshadowed what radio faces today. Just as Napster cut ahead of promo CDs, TikTok now catapults unsigned artists into the charts before a station’s music director has even heard the track. The struggle to stay relevant in a world where audiences move faster than industry pipelines is ongoing.
But in 2000, none of that was clear yet. What was clear was that a leaked Metallica song — ripped, shared, and uploaded by fans — made it onto the radio before it was supposed to. And for a brief moment, the future of music sounded like a 128 kbps MP3 playing through FM static.
