When I was growing up, the people who liked the Beatles, I didn't like, so I didn't pay attention to them.
When I sit down to make a set list I usually think, 'We'll build it up here, take it down here, go into a quiet section here, explode here,' in a way that there's a flow and it doesn't feel like shuffle on an iPod.
