Bono speaks at Georgetown University

"Pop is a very disciplined record. The song structures and arrangements are really classic: it's just the sounds and the mixes that sound odd, and I think that combination is what great pop music is all about. All my favourite records are like that: you just can't tell how they're put together. 'Strawberry Fields Forever' for example, it's one of my all-time favourites, but it sounds so bizarre, even though it's such a classic song. That's what interests me, that feeling you get when you don't know where to begin in finding out where a song came from." - Edge, 1997
