It's a tough thing to know that when you're making your album, you're going to end up collaborating with, say, Wal-Mart, on your artwork. That just sucks. And the pressure behind getting the numbers real fast is, to me, dizzying.
Fundamentally I feel that there is as much difference between the stage and the films as between a piano and a violin. Normally you can't become a virtuoso in both.
