another song i need help with: all i have is the beat

Can anyone tell me what song this is?
http://www.freewebs.com/jurgenhorst/mysterybeat.mp3

it was on the ad for the simple life marathon on australian fox8
i know i've heard it before and it's driving me crazy!

It's not rock this party by bob sinclar or move your body by nina sky
can someone help me?

From that beat I think that it might be "Someone else" by Allegro feat. L.V. Fresh Game & Cokni O'Dire...
It actually starts in a different way, but the beat near the refrain goes almost like yours ... Mumble mumble...

It may be too obvious, but it sounds a lot like "Temperature" by Sean Paul
