"Edge made me listen to [our old material] for The Best Of, and I was bracing myself, cause I think I sound like a very opinionated girl. Just screaming my head off. But then I actually listened to it and I thought, 'My God, there's pure joy here.'"
- Bono, 2000
The song 'Bullet The Blue Sky' is musically supposed to represent the bombings of El Salvadorian towns by US planes during its civil war.
