This is from Ice Cube's "The Predator" album.  This song is also featured on the new GTA game: San Andreas.  

It is in 4/4 time, and this is the rif repeated throughout:

----------10--10--8---6h8p6-5h6p5-3-------
-----8-11---------------------------------
---8---------------------------------5----
-5--------------------------------------0-
-6-----------------------------------6--3-    
-0-----------------------------------5--0-   Then this quickly starts right over again, after strumming the last chord.

I am unsure about the chords, but I am 100% correct with the melody.
