Madworld - Originally found on the Donnie Darko soundtrackI agree - it's a great song - better than the original version by Tears for Fears. The Gary Jules version you refer to which is better than the original, is also on the Gary Jules CD "trading snakeoil for wolftickets", which is probably a more worthwhile cd to buy than the Donnie Darko soundtrack (though it's worth having too).
Unfortunately don't have another nominee for "comeback tune"
