New Music: Rihanna - S&M (Remix) (Feat. Britney Spears)

Rihanna's latest single, "S&M" is currently at #2 on Billboard Hot 100, and now it looks like she hooked up with Britney Spears on the remix of the track.

I'm not feeling at all, maybe I have to listen to it a couple times. Britney's voice on the track sounds off to me.  The song is on iTunes now.

Take a listen below.
