Identify this song without lyrics..?

It's a song from a video, I've heard it in two places, In this video and in a porn video (Don't laugh )

Theres two songs in this video that cut eachother off, One sucks, and one is great.

The one i want to identify comes in at around 00:18, and is cut off at 00:39, Returning again at 00:59, then cutting out again at 1:12, Returning yet again at 1:27 and staying until the end, anyone know what this song is? It's killing me, i must have it.

Thanks.
