I can go from one extreme to another, from playing at the Sydney Opera House on the Songbook tour to shows with Soundgarden at Voodoo Fest, all in a week.

If you sold a million records, the only way you could be disappointed is if the guy down the street sold seven million. But you've got to start dodging bullets once you've sold that many records, because everybody wants to kill you. We're not in that position. We can still be very successful and not have to worry about wearing bulletproof vests.

If you are trying to think ahead musically, it is not going to help you. It is better to ignore what is happening melodically and just look at the little dots coming at you and the corresponding colors and try to do it at the right time.

In the United States, workouts tend to focus on body image and how you look. For me, it's really all about the brain.

When you're having a conversation with someone who, despite his brilliant medical career, says he's going to produce the film, you think, "How's he gonna do this? Is he insane, or is he really going to pull this off? It might be both." It's really amazing to see someone do what he's done.

Ever since I can remember I’ve had positive and negative fan reviews. And whether it was positive or negative it wasn’t always based in reality or what my perception of the music was. But judging from playing these new songs live and my feelings on the record [Scream] – and it’s a great record – there is definitely an audience for it. Also, I don’t really go to clubs so I don’t know what sounds are made there.

My first favorite band that made music important to me was the Beatles. I was a little kid. I didn't know who was singing what song or who wrote what song.
