Here's an example of what the world needs less of: twee, novelty covers of rap songs by cutesy indie duos. Not only does Karmin's "cover" suck the vibrant life out of Chris Brown's "Look At Me Now," but it does so with a knowing, smary attitude. (Amy Heidmann's strange vocal inflections and bug-eyed emphasis scream, "This is funny! I shouldn't be singing this but look ... I am!") This cover offers nothing new other than a Starbucks-ready version of a song that should never be played at Starbucks. The group also changes the lyrics to a PG-rating (their term, not mine), and it transforms a song built on brute force (all three original artists — Brown, Busta Rhymes and Lil Wayne — attack Diplo's beat with a fiery menace) into a Kidz Bop sing-a-long.
