New music: Rihanna feat Britney Spears – S&M

A few days ago, Rihanna asked her millions of Twitter followers who they'd like to see her collaborate with. Apparently most of them replied "Britney Spears" and now, through the wonder of crowd-sourcing and probably a few high-powered label negotiations, we have a remix of Rihanna's current single S&M featuring a whole new section sung by Britney Spears. Britney's verse carries on where her recent Femme Fatale album left off, all innuendo-laced lyrics and slightly uncomfortable (in all variations of that word) imagery: "It's your turn to hurt me/ If I'm bad tie me down/ Shut me up, gag and bound me". Considering the original was edited to remove all mention of "chains" and "whips", it's not clear whether anyone's banking on this version being played on the radio. Also, it would be hard for Rihanna to continue the claim that the song is about anything other than sadomasochistic sex, unless "feel the pain on your skin" is about tattooing and "just one night full of sin" is about watching EastEnders while overdoing the chocolate biscuits.
