Rihanna's album has consistantly been in worldwide top since its release, forget about openning week sales. Britneys new album is track far behind the circus which went on to sell 4million. Loud has already reach that number and will continue to sell. Femme Fetalle wont be able to compete with loud becos in the worlds second biggest market (the UK) its number 29 after only 4 weeks, whereas rihanna is number 5 and has sold 1m in that territory already. I'm no stan of anyone but its obvious that Rihanna is gonna come out on top in the end
