karmin covers chris brown lil wayne busta rhymes... or maybe by anyone. In Karmin's cover of Look at Me Now, by Chris Brown feat. Lil Wayne and Busta Rhymes, Amy sings and raps all the parts with impressive vocal dexterity. Pay special attention to her flow on the super-fast Busta Rhymes part in the middle of the song, because she totally kills it. George Watsky and Mac Lethal had better watch their backs -- we've got a new fast rapper in internet-town.
