I'm interested in the way the whole cultural landscape can shift over time. Okay, this will seem like a silly example, but look at the whole discourse around "selling out," a concept people say is irrelevant because there's no more distinction between mainstream and underground, inside and outside (which I don't really believe, but that's another issue).
I didn't want to be a big record mogul and all that stuff. I just wanted to write songs and make people laugh.
