"The songs on Zooropa are not classics but they are more experimental and interesting than classic pop songs. This is something we don't necessarily care to do anymore. We don't go down the road with a piece of music just because it's unusual. That's not enough for us now. We want something that's potent and some of these songs are not particularly potent."
