Hollow Man (2000)

Plot hole: There must be a lot of dumb scientists in Sebastian's lab. While defibrillating the invisible gorilla, (s)he becomes completely visible for a moment. However, not once do the scientists consider that applying a mild electrical shock to the system renders the invisible animal visible again - that electricity may be the key to the whole invisibility problem. They don't even comment upon the fact that the gorilla does become visible.

Sebastian: I can't take much more testing.
Matt: I know how hard it is.
Sebastian: Bullshit. You don't know anything.
Matt: This isn't easy for any of us.
Sebastian: Fuck you, Matt! It is easy for you. I was to be in phase-shift for three days. It's been ten fucking days, all right? Ten days of tissue tests, radiation tests and your fucking needles! I can't fucking take it anymore.
Matt: What I meant was.
Sebastian: Fuck what you meant! And don't ever... Don't ever tell me how hard you have it.

Trivia: Whenever Sebastian is invisible and interacting with the other characters, Kevin Bacon's voice would be broadcast throughout several speakers randomly hidden throughout the set. This was done to make the reaction more genuine, since the actors would honestly not know where his voice was going to come from next, just as the characters would not know where Sebastian was.

Question: Two songs were playing in Sebastian's car. One song as noticed twice was 'Power Struggle'. He was listening to another song later on in the movie. What was the name of this song and who plays it?
