Well said biggies real appeal was that he stayed true to who he was. with all these fake cats in the game today it tends to have even more appeal now then when he was alive.
I never thought of him as goat but I did enjoy his rawness. I personally wouldnt put pac on the goat list either. Pac didnt stay true to who he was Pac was life imitating art. He had a decent flow and good lyrical content but a goat?
My Goat List in no particular order accept for Rakim top of the list. You will notice these are all MC's.
Big Daddy Kane
Nas (the street prophet)
Kool G Rap
Slick Rick (the true story teller)
GZA (sharp lyrics, smooth flow)
Run DMC (A lot of cats seem to leave them out of there GOAT list. These cats made it possible to have a GOAT list in hip hop. Rev Run to me is the true definition of an MC)
Kool Mo dee (brought us battle rap.)
