It's been a while since I've watched the movie, and I don't have a copy of it on hand to refer to, but I'm somewhat certain that "7 minutes" is the song you're looking for. It's the 10th track on Future Blues. They've got a snippet of the song here (
http://jameswong.com/ykproject/disc/disc.php?cd=bebop_futureblues) so you can double check me on that (And if I'm wrong, they've got bits of the other 17 songs on the album so you can find the right one. One of them has to be right, right?)
