There's the famous thing that the A&R man from the record company is supposed to do: He's supposed to come into the studio and listen to the songs you've been recording and then say, 'Guys, I don't hear any singles.' And then everybody falls into a terrible depression because you have to write one.
There isn't much I find interesting to write about in middle-class life.
I do write songs with a political dimension to them sometimes, but I'm always slightly appalled by it when I do.
