We are at a crossroads in the music business: with the rise of the internet, the world we live in has changed, and the past is not coming back. But I see the glass as half-full: the internet and social networking are new avenues for the next Bob Dylan to be born on.

Music has always carried me through times of loneliness. So when I make music, I like it to make people who listen to it feel like they have a friend who reveals something personal to them, rather than trying to be like a god up on a pedestal.

The stores and the things like that, the business side of things came out at the point when, I'd say probably in the early '70s, it looked like the year of the singer-songwriter was over, 'cause music changed in our time and the spotlight was out.

You need music, I don't know why. It's probably one of those Joe Campbell questions, why we need ritual. We need magic, and bliss, and power, myth, and celebration and religion in our lives, and music is a good way to encapsulate a lot of it.

We're not uncomfortable with it, and we've already been through enough of the music business where I'm not really worried that commercial success is going to in some way - we're already past saving, you know what I mean? It's too late for us.

Politics can be strengthened by music, but music has a potency that defies politics.
