U.S. Charts Update – March 16, 2011

Despite its great iTunes positions and airplay updates, Rihanna’s current single “S&M” is down to No. 4 on the Billboard Hot 100 (behind Lady Gaga, Cee Lo Green and Katy Perry). Next week’s chart will be based on Monday-Sunday (March 20) updates, so let’s keep working hard!
RiRi has recently thanked RihannaNavy on Twitter for the support:

Love u RihannaNavy! We fackin it up! I see yall representin wit S&M! Get S&M on itunes!
