It's from the scene near the beginning where it shows Macaulay Culkin/Michael Alig's flashback. He's resting his head on a railing and this song is playing for about 30 seconds. Kind of an electronic, "be-doop ba-doop" sounding song. I know, I'm vague.
If anyone has a clue, I'd be super happy.
-EDIT-
the scene is also the one where he's in a mall and everything is moving super fast.
