Help with a mystery song

Hey all, I have a clip of music that I am trying to identify:

I think it may me 2Pac but I just can't find what song it is, any help would be greatly appreciated

Thanks in advance

p.s. I have tried using Shazam and Midomi to identify it with no luck

It sorta sounds like Ja Rule, but I'm not sure of the track.
