Rihanna

Even if she fell just short of our top 50, Rihanna topped other charts. Her seventh studio album, Unapologetic, debuted at No. 1 on the Billboard 200 and was her first No. 1 album in the US. Her hit songs "Diamonds" and "Stay" dominated radio waves, and she embarked on a minitour, 777. Rihanna was the talk of the 55th Grammys, not only for her "We Found Love" win, but also because she attended with ex-boyfriend Chris Brown, from whom she's since split. Rihanna kicked off her Diamonds World Tour in March.

Rihanna ranked 14th in the Phenoms category.
