11. Chris Brown f/ Busta Rhymes & Lil Wayne "Look At Me Now"
And now for some pop shit. Or was it? Diplo, Afro Jack and Free School crafted a beat so indestructibly futuristic that it became damn-near inescapable. "Look At Me Now" has pretty much stayed in heavy rotation from the moment it debuted on 106 & Park this past February 1—and see if it doesn't shuts shit down at your New Year's Eve party tomorrow. Not only did the song bring Busta back to post-"Scenario" levels of ferocity and allow Weezy an opportunity to go dumb like the Three Stooges. It also launched Karmin's career and even gave Justin Bieber a chance to prove he could spit too. Plus it afforded Chris Brown an opportunity to tell haters to say hi to his dick. Leggo!
