4. Britney Spears
Following a disastrous judging spot on The X Factor USA, Britney looks set to return to her music with album number 8 on the way this year. Britney left many cold with her X Factor USA spot, featuring uninspired comments and a general sense of awkwardness. However since leaving Simon Cowell's American train wreck, Britney is back to the top of the charts with will.i.am's worldwide smash, Scream & Shout. It may be an awful track, but it is still a pleasure to see the iconic singer once again on top. With the new album supposedly featuring a similar sound to her stellar album, Blackout, all signs point to Britney to save pop in 2013. http://www.youtube.com/watch?v=kYtGl1dX5qI
