I heard a great line a while ago. Sean Ono Lennon was being interviewed. He was asked the inevitable question that every songwriter is asked: Are your songs autobiographical? His answer has stayed with me as a reminder of what songs really are. He said… “Songs are myths about things that have happened to you.”
I can´t think of a better way to put it. We all write about our lives, our feelings, the things that happen to us. But the idea of myth-making is what´s important here.
