Complex has been putting out a lot of these lately -- 11 rappers who were once slept on but no more (Elzhi, Masta Ace, Sean Price), 11 rappers who never dropped a classic album (Busta Rhymes, Big L, Ras Kass, Canibus) -- and now they got 50 most slept-on rappers of all time.

somehow Big Pun is #2 and AZ is nowhere on the list, even though he's the most underrated MC ever. but RA the Rugged Man, Cormega and Killarmy are on the list
