And John Lennon deserves to be in there on the strength of his solo work & the Beatles deserve to be in for being the fucking Beatles! Paul McCartney probably should've made it in twice to for his solo work & work with Wings.
That's fine if you think that, it's your opinion. I just disagree. I don't think it's fair for ANY ARTIST to be on the list twice. That's ridiculous.
And nah, I don' think Tupac deserved to be in the Top 20, maybe - & that's a big maybe - the top 50.
It's not a maybe IMO at all. He is the most successfull rapper of all time, and that's a fact. He owns the distinction of releasing the first double album in rap history. You were talking about how NWA had such an impact they got a letter from the FBI. Well...Pac was surveillanced by the FBI. Pac is probably the most recognizable rapper in the world. IIRC, he also holds the distinction of being the first rapper to go diamond (I'm not positive on that, so if someone can prove me wrong, then go for it and so be it). He is heralded by his own colleagues as being the best and "realest" rapper ever. He's definately one of the most respected and honored. And almost a decade after his death, he's STILL one of the most active artists in the industry and is STILL very relevant to today's society.
If all of those qualities don't constitute being labeled as one of the Top 20 musicians ever, I don't know what does.
Oh, not to mention that AT LEAST 2 of Pac's albums are considered classics, and there's one album that is or isnt' classic depending on what Pac fan you talk to.
