Virtually everyone who has seen Donnie Darko has remarked on the haunting, acoustic version of Tears For Fears's Mad World with which the film ends. It is by Gary Jules and the Group Rules - listen to a bit of it. Nice, isn't it? It's on an album called Trading Snakeoil For Wolftickets, but don't let that put you off. It's also on the Donnie Darko soundtrack.
