I'm sure from memory the backing track is Bizarre Inc - Playing With Knives, but not sure what this new track is called...although I know the video you're talking about!
Edit:
I've just spent the past 20 minutes trying to figure out what it is on the net...and it is...
Big Bass v Michelle Narine - What You Do (Playing with Stones)
