My first three movies, I didn't start editing until we were finished shooting. That's unthinkable to me now.
I think it's absolutely possible to write a song and go somewhere where no one's been before, uncharted territory. In terms of content, I see limitations where there should be none. I know there are things I wouldn't write about, but that shouldn't be the case. You should be able to make a song out of anything, out of any situation.
