I used to see songwriting like editing a film or something. You can edit music like you can edit a film. Or if I was painting or making a picture or something, that night I could sit down and write a song. I think it really helps to break things up. Sometimes when you sit down to write songs, you write three or four songs in a row feeling the same sort of vibe. But if you stop in-between that time and change something, you break the pattern – you prevent yourself from unconsciously falling into a format.
