6. 2 Chainz Debuts at No. 1
When 2 Chainz announced his debut album, Based On A T.R.U. Story, everyone wondered if he could hold his own for an entire album or if his run as rap's most recent novelty would come to an end. In the end, 2 Chainz prevailed, stayed true to his style, and scored the top spot on the Billboard charts. Plus, the video for "Birthday Song"—you know, the one with "big booty hoes" and Kanye riding a bicycle in leather pants—was just too awesome.
