What was the music for the credits in the Hentai movie, Slave Market: Myia?

You can watch it at MetaHentai.com
Anyways, there's three parts, and in the third one(Myia) they have the
credits, like at the end of a movie.
And it had the coolest song I've ever heard!
But I don't know what is called!!!
Can you please give me the name...?
