Check Out Katy Perry's New Single, "Roar"

'Roar' is the first single from the anticipated release of Perry's fourth album, "Prism". In this newest endeavor, Katy is shedding her sugary, outlandish persona and adopting something darker. 'Roar' does have the twitter-verse in a tizzy due to it's resemblance to Sara Bareilles' new song Brave.

Re-defining yourself isn't easy, good luck Katy.
