Colbert was having trouble deciding his votes for the Grammys, saying things like "The Arcade Fire? Ehh, they went on the Daily Show, f*ck em." Then he invited The Black Keys and Vampire Weekend's Ezra Koenig for a sell-out off!

Goodness gracious, Vampire Weekend obviously wins this battle with their widely-hated Honda and Tommy Hilfiger commercials that ran non-stop over the holidays. (Although, The Black Keys' music is featured almost everywhere.) The Keys played it cool per usual during the appearance and Ezra came across much less douche-y than advertised. But really, I can't wait to see what Carles has to say about the whole thing.
