Of course it's "Maybach Music II" (the one with Kanye West and Lil Wayne). It's the most enjoyable song in the series, features two superstar rappers, and J.U.S.T.I.C.E. League's instrumental best captures the grand, lavish feeling that a Maybach is supposed to have. The original comes closest, but T-Pain's irresistibly catchy chorus gives the first sequel the edge.
