I constantly get people telling me I should be selling as much as Katie Melua... but there's a reason she sells that many and I don't - she makes music that's easy on the ear and even easier on the brain. She's the perfect good girl in the middle of the road. I'm not keen to make things too easy for anyone. I like to provoke a response, whether that's someone telling me they love what I do or throwing a bottle at me. The trouble is that the bottle-throwing faction won't buy the album. You've immediately limited your audience.
