Katy Perry kicks off her hotly anticipated "Prism" era with a stylistic return to the arena-sized singer-songwriter formula that made her debut "One Of The Boys" so remarkable. Fans have already had a heyday of comparing the self-empowerment anthem's sound to Sara Bareilles -- specifically the singer-songwriter's current single "Brave" -- but that doesn't discredit the artistic statement implicit in the song's message. Admittedly, the lyrics rarely rise above easy clichés and rhymes ("I went from zero / to my own hero"), and the stomping mid-tempo beat leaves a little to be desired in the BPM department, compared to Perry's previous dance-pop bangers. However, "Roar" marks the first time Perry has led an album cycle without a novelty song ("I Kissed A Girl," "California Girls"), and the new single includes one of her strongest vocals in the process. Plus, the song's staccato-heavy, shout-along chorus sounds custom-made for a live setting -- and a really killer remix.
