Most people who believe Tupac is overrated, say that, because they claim that he isnt lyrical, he has a garbage flow, he was a fake gangster, etc. However Tupac was lyrical, in fact, Tupac has some of the most meaningful songs in the history of music, not just hip hop.
I'm not even going to argue about his flow, simply because people have different preferences when dealing with rap styles and techniques. On the contrary, I believe Tupac had tremendous lyrical (see 2pacalypse Now, MATW, etc.) capabilites and would have developed a more advanced vocabulary, as he got older.
Fake Gangster? I laugh everytime I hear this claim... Tupac was more GANGSTER than any rapper rapping TODAY... you people who make these foolish claims, seriously need to research what Tupac was apart of and how ACTIVE he was in the community. Back in the 90s, damn near every OG (Political Prisoners) across America wanted to make Tupac a Chief, so to speak. However people are going to have their opinions and I understand that.
