If you think of any long-term artist that makes music throughout several decades, you would hope that it's autobiographical and a form of self-expression, and that's certainly how I approach my music.

I would agree with you that there's 90% imitation and 10% innovation. That's true of any genre.

I always managed to fly a bit below the radar, but high enough to avoid colliding into anything.

In certain cases I don't want to sell tracks individually; I want to only sell the whole album. With simple things like that I just don't get any response [from iTunes]. I don't want to kill iTunes - I just want to offer my own retail experience in my own tiny corner of the Internet.

Just like on Guitar Hero, there are things that are similar and things that are not similar at all. When I first played DJ Hero, I wasn't very good. The control surface is similar in some ways to a turntable, but in other ways not at all the same.

I remember when the big shift happened in 1996-97, when suddenly it dawned on the music community: 'We should license our music to commercials and sell out for all intents and purposes. It doesn't really matter.'

The conventional wisdom of fandom is that you must give your fans anything they want. But I've never felt that that's a healthy attitude - and that comes from being a Star Wars fan.
