Blac Haze he stresses his throat trying to sound like pac on the other hand tha realest naturally sounds that way although he copies pac's lyrics and ablibs but I don't care about that anyway he's starting to get away from doing that as much his last mixtape was dope you can dl it off his myspace at least he can make up decent lyrics up himself unlike ja rule who just sounds shit singing anything. 50 cent an them over rapper's are just fagz trying to mock pac just look what g-unit an master p have done to pac's music hell master p even tried buying original unreleased pac songs an getting krazy to sing them.
but if we take the realest and blac haze as an example, they and pac have nearly the same voice and both of them are rapper, and pac was born to spark the brains...
