I don't write songs that don't affect me on some level, because I figure if I am not moved by it, if its not something that I have a longing to celebrate or to be reminded of, if it doesn't affect me, then how can I possibly think it is going to affect somebody else. My touchstone is write something that matters.
Without black, no color has any depth. But if you mix black with everything, suddenly there's shadow - no, not just shadow, but fullness. You've got to be willing to mix black into your palette if you want to create something that's real.
