In May 2000, Metallica's Lars Ulrich delivered 13 boxes to Napster's office. Inside were the screen names of 335,435 users who had shared the band's songs for free. Napster agreed to block them. To many, it looked like Metallica against its own fans. In the video below, Ulrich explains why he did it. "Napster hijacked our music without asking." It started with a leak. Unfinished versions of "I Disappear," a song for Mission: Impossible 2, were already playing on US radio. The band traced them to Napster. On April 13, 2000, Metallica sued. In 48 hours, Ulrich said, over 300,000 users made 1.4 million free downloads of its music. Napster said it stored no songs and only connected users. Fans called it sharing. Ulrich rejected the word. "If I share a sandwich with you, I'm left with half a sandwich." That September, Napster's founder, Shawn Fanning, walked onstage at the MTV Video Music Awards in a Metallica T-shirt. He said he had borrowed it from a friend. Metallica and Napster settled in July 2001. That same month, Napster's free service went dark. In 2003, Apple opened the iTunes Store at 99 cents a song. Thirteen years later, Ulrich put it this way: "It's not about money. It's about control." He knows how he will be remembered: "It'll be in the first five sentences of my obituary." So was Metallica protecting its music, or turning on its own fans?
