I don't know if there's any formula. I'm not sure I believe in that, to be honest. I don't know if there's any rhyme or reason to music. Sometimes it hits and sometimes it doesn't, really.

Nothing wrong with pop.

I think if you're a creative person, then you're always kinda looking to move things along - 'Where else can I go? Where can I take this?' From painters to photographers - anything creative in the arts - if you're a true artist, I think you'll always look to do something else. 'Where else can I go with it?' Do you know what I mean?

It's important to know all those things, but part of our jobs is to move people along and to make people excited to buy music or buy clothes, and give them enjoyment, I think, too.

Coming from a little suburban town, I wasn't a hip city kid. I was quite the opposite, really. Songs like 'Saturday's Kids' rang a bell for kids all over the country. That song was about the kids I grew up with.

My own personal theory is that all popular music, in whatever form it is, to me, it all comes from Africa. Whether it's filtered through America or whatever - African-American. But I still think there's something in that roots music that's very, very African, and I think that's what unites people.

I still love playing music. It was all I ever wanted to do, and I got the chance to do it.
