Speaking to VH1 Classic's That Metal Show, he said: "I sat there myself and downloaded Death Magnetic from the internet just to try it.
"I was like, 'Wow, this is how it works.' I figured if there is anybody that has a right to download Death Magnetic for free, it's me. I sat there one night at my house with about six of my friends and a bottle of wine.
"We found it — this was like two or three days after [Death Magnetic] leaked. I was like, 'You know what? I've gotta try this.' So we sat there, and 30 minutes later, I had 'Death Magnetic' in my computer. It was kind of bizarre."
In 2000, Metallica filed a lawsuit against the original incarnation of Napster after they discovered that a demo of their song I Disappear had appeared on it.
