If you listen to some of the stuff Biggie's sayin at the end, it sounds like the couldve been recorded while Pac was alive. He's sayin something like:
"And to the nigga talkin on the westside, come see me. Come see me, niggga"
"The only reason I aint naming no names is cause I dont want to give these bitch-ass niggas the chance to make a record coming back to sell a few units. Faggots!"
