Me and a friend of mine found a website fluffertrax.com which, as the name suggests, houses porn music. I think the music used in porn films is AWESOME! The wacca wacca bass....but it doesn't really have a genre, so its just "porn music".
I think the names of some porn films are great. Stufflike "Wide Eyed Sluts" And "when Harry Tossed Salad" They make me laugh.
