35. "Until the End of the World"
This dense, tribal-stomp track – which Bono described as being inspired by "a conversation between Jesus and Judas" – defines U2's nothing-is-simple dictum when writing songs. Bono initiated the riff for a song called "Fat Boy," but it didn't go anywhere – until the Edge picked up on it and refashioned the part as the band's contribution to the soundtrack for Wim Wenders' film Until the End of the World. Not only did the re-recorded, revved-up new version wind up on U2's own album as well, but, as the Edge has said, "We told Wim, 'You can have it, but we want it too. ... By the way, we're borrowing your title!'"
