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.
I was blonde most of my life and I had to dye my hair for a role. I couldn’t believe the difference when I went red. I just felt ‘wow, I’m home’. It’s great. You do something stupid when you’re blonde and you’re dumb. Do something stupid when you’re red and you’re a character.
