I maintain that if you're a novelist and you go into an art museum, you'll come out a better novelist. And if you paint a picture for an hour you're a better actor at the end of it.
I love listening to Radio Head's 'Everything in its Right Place' because it's all major chords, it makes you feel really good. It's soothing, it's got a beautiful voice, crazy textures. When I'm down I listen to that song and it really makes me feel good.
