Yeah, it's a song by DJ $crilla called, "Gamma Phi Beta Anthem". My Beta Lambda girls danced to this song at this year's formal recruitment rounds.
I downloaded the song to my iTunes directly from DJ $scrilla's website a long while back. It sounds like his website is no longer running? Well, you can hear the song here...
