I'm no lawyer, so I don't know. But nice content, I hope it does well for ya!
From a purely "i don't really know shit" point of view .... you're not making money off of the music, it is just an unfortunate side-effect of filming porn at a party, so I wouldn't worry too much about it.
Besides, rappers love porn, and it's mostly rap/hiphop in the background, right?
