I did an album a long time ago called 'Replicas ' which was entirely science-fiction driven or science-fantasy. Since then it's been a song here a song there. It's not really a constant theme. I've written far more about my problems with religion with God and all that.
You only get one album. You only get one single. You get one shot in music. But I have a million different dreams. Why can't I go out and try to achieve them all? Who are you to say I can't?
