More of my songs are intended to be funny than almost anyone else. Sometimes maybe it cheers me up a bit. I've got a distance from it. Sometimes what I'm writing is more important to me than the rest of my life. It's more important to me that I'm writing well than anything else.

I've often written about places that are totally different from anything I know. Sometimes they turn out better.

I've worked with a band, and it's nice to have someone to travel around with, but I didn't like it as well on stage.

I've written a song for Prince. I never showed it to Prince, but just to see if I could do it. At the time, when I sort of knew him, he was recording a song a day. I wondered if I could do that. So I wrote it.

Writers have always liked my stuff, pretty much. That's what I wanted - I think my goal wasn't to get rich and famous, necessarily, though I cared about that. I always thought, "Oh, this could be a hit," or "that will sell records." But the first thing I wanted was that people who knew a lot about music, or had taste-making qualities, they would like my stuff. Writers, people like that.

But I don't want to sing everything out of the side of my mouth, I want people to understand what I mean.

If you have a kid and you try irony out on them, they don't get it at 7, 8 years old. You can't really hide the Internet from kids. It worries me some particularly because I've done Disney and Pixar stuff.
