KWT: Rihanna - "Diamonds (Remix)" [feat. Kanye West]

Yeezy taught Rihanna well. If you've got a multi-platinum single on your hands, throw Ye on the remix to widen the demographic by a few milli for good measure. Ri-Ri does just that for her Unapologetic single "Diamonds," releasing a Kanye assisted re-up without any prior mention.
