"Every time I write a song, it's different. I'm all about the rhythm of the words and the melody. Musically, you gotta have a throbbing pulse going. But as far as what it's all about, there's a million ways to go. You have to invent a new code for every song. Then you have to break it. It's like Scrabble or a crossword puzzle on steriods. I could talk about the process for days. But it's never dull and there's no one way in."
