I beg to differ, but since that's your opinion I'm going to respect it. Honestly to me, Nas has about four (disputable) classic albums out of his whole entire catalogue; excluding unreleased/collaborations.
So 4 classics, and lets say 4 good albums and the rest been average. I mean, any other rapper would kill for that level of success.
Over 23 years as well. How many rappers from the early/mid-90's are still poppin like that? Obviously you got someone like Jay but a lot that are still active don't even get the attention Nas does
Jay from the mid 80s.
