Good post. Tie my hands, Shoot me down and Mr Carter are 3 of my fav Wayne tracks but he still aint on Eminems level IMO. Im not saying he's not good because he is but I'd say Eminem is a top 10 ATG (arguably) where as I can quite easily think of 10 emcees id have before Wayne, Em being one of them.
Before you ask here are emcees I personally would put before Wayne...
LL Cool J
There's more but I gotta go back to work. You get my point
