Can't Find This Rap Song

I heard this rap song on the radio last friday around 8-9pm (U.S. East Coast time zone). I didnt know which radio station it was.

I only know the chorus went:________ fire me up! (x4)
________ set it off! (x4)

I think one guy was rapping the first part and another guy was rapping the other part of the chorus.

Does any1 have any ideas?

set it off by kardinal offishall ft. the clipse

Yeh, that was it. I feel foolish

Thanks
