The purpose of art is to stop time.
You don't write a song to sit there on a page. You write it to sing it.
You don't count the dead, when god's on your side.
Mama's in the factory, she ain't got no shoes. Daddy's in the alley, he's looking for food.
Basically you have to suppress your own ambitions in order to be who you need to be.
A song is anything that can walk by itself.
