2Chainz being more popular than Nas means nothing. Nas been around 20+ years and 2Chainz is a new rapper. You might as well say "let's see where 2Chainz career is 20 years from now".
Fred.
The amount of years either has been around isn't the point. If people truly believe that record sales = popularity, Nas is more popular according to them. In 2012, would that be accurate.
2Chainz isn't a new rapper. He's only new to people who aren't familiar with Playaz Circle and him originally being Tity Boi.
