Crank High Voltage

Hi, I'm looking for the song at the end of the movie, right after one of the porn stars says: "lips like this don't come for free".
While the song is playing, you here the voice of the guy's head from in the watertank saying "what the fuck are you talking about".
I really hope someone can help me, I can't get this song out of my head; & I've tried every possible way to find this song.
( obviously, it's not on the official soundtrack )
Also, it's the song right before the song "Fruhlingsstimmen" by Felicie Huni-Mihacsek.
Greetz,
Tom
