RIHANNA RENAMES S&M SONG TITLE

I was wondering how "S&M" was going to make it on the charts.



But apparently, the title changed to "Come On."

It's not clear who made the change, but that hardly mattered to RiRi, who took to her Twitter account to express her outrage.

"Are you f---ing kidding me??? I'm on it!" she wrote in one tweet after being asked by a fan about the new title. When asked by another fan if she was OK with the change, she replied, "Absolutely Not!"

A spokesperson for the OCC (the British-based Official Charts Company) wasn't aware of the "S&M" flap when contacted by MTV News, but did point out that, on the version of the Top 40 that appears on the organization's Web site, the song retained its original title.

In the latest edition of the U.S. singles chart — the Billboard Hot 100 — the song sits at #66 ... under its original title.
