I had to go into a studio and compose and write and press up 12 songs in 14 hours. When you're recording a song from scratch it takes you 14 hours to do just one song.
The trick to writing for people is, you have to be able to turn them on in your head. And know how they'd word something or how they'd inflect it.
But one of the hardest things for me to do was to access anger. I could do it on stage. But when I did it on film it was hard for me. That probably has to do with the intimacy of film. And my own personal issues with expressing anger. So I had to learn how to do that.
