Did anyone watch Beyst's Rock in Rio set? Did any song sound weird? If she hinted Xo to the crowd, it's possible the instrumental of the single was looped somewhere in the set. She sneak introduced Bow Down when she sang Countdown at Revel.
But people, who would have known out of ALL people Miley Cyrus is blocking Britney Spears on iTunes? And that Katy Perry would block Lady Gaga? AND Eminem's new single being a mediocre hit. I guess times are changing.
"Work Bitch" takes risks that were not present on the (highly enjoyable) "Femme Fatale" singles -- and Spears has earned the right to take risks. This is not paint-by-numbers pop. Go tell the police, the governor, the state congressman, the barber, the guy who works at your local Burger King -- go tell whoever you need that Britney is back.
