5. Lil Wayne has worked his ass off touring to get people excited about his music again.
If you think about Wayne's buzz before Tha Carter III as compared to his buzz before Tha Carter IV, it was much different back then than it was this time around. In 2008, Wayne had so much material floating around on the Internet and such a big buildup to the project that people couldn't wait to cop Carter III. It's one of the reasons it flew off store shelves. In 2011, that same buzz is still there, just in a different form. Wayne's I Am Music tour has put him front and center in dozens of different cities throughout the last year. It's given the rap blogs tons of material, given rap fans an opportunity to reconnect with Wayne, and given Wayne the chance to sell himself to the people again. And it's paid off. It's paid off big.
So while it seems like Watch The Throne should have outsold Tha Carter IV, the truth is that hard work pays off. And while we're sure Jay and 'Ye worked hard on WTT, Wayne worked just a little bit harder at actually getting people to buy his album. So, should we really be surprised at how many albums he was able to sell? Like it or not, Wayne wins again with Carter IV.
