"niggaz4life" production wise, and people will admit dre produced that, but won't admit he produced the chronic, even though it sounds like the same type of production.  

real spit right there.  It's VERY obvious when you listen to Niggaz4Life and Chronic that production wise, they both came from the same pot of soup.  You can tell that Dre was still in that frame of mind when it started work on The Chronic.  Hell, I wouldnt be surprised if some of the ideas that popped up on the Chronic werent originally left over from Niggaz4Life (Pure speculation though)

Niggaz4Life ='s Pre-Chronic! (Undeniable)
