I'm not big on rap, to be honest. I just don't get it. It's angry people shouting. I like a song, melodies, people singing.

An artist or writer always has to move forward. All the time you're trying to improve yourself, or at least look at ways to improve things or make things better. I'm not really one to harp on previous records. I'm always looking forward to what I'm doing now, and what's ahead.

I never get too many problems. You can never please everyone anyway, obviously. And some people take the easy route and just play the greatest hits, and their audience is happy to hear that as well, and that's fine, but it wouldn't please me. But it doesn't trouble me.

You have to keep challenging yourself. I've always tried to do that, and I'm not saying I've always been successful. Maybe I've rewritten the same song; it's inevitable, but I've always been mindful of taking the writing somewhere else. You can't stick in your little comfort zone.

When I discovered blues - I was 12-years-old - I didn't discover it in America where it was from; I discovered it from Fleetwood Mac - the original Peter Green Fleetwood Mac, Saveloy Brown - like British blues interpretations of it,' which then, when I started the liner notes and seeing all these names, I was like, 'Who's Willie Dixon?' Then I go to the record store and ask the guy there and he goes, 'Oh, you don't know anything.' And so, to me, that's the root of most of it anyway.

There's always something in most world folk musics that always seems connected; whether it's a bagpipe or a tambura, there's always some sort of drone instrument, and there's always percussion.

I love soul music, that's my real love in life and in whatever shape or form it is.
