If you loved Sara Bareilles's "Brave" and Katy Perry [1]'s "Roar," prepare to get hooked on a superior melody. With its soaring chorus and message of personal transformation, I play this to either get in a good mood or keep my positive mindset going. If it's released as a single, you just might hear this on the radio 24/7, so keep your fingers off that repeat button. — Nick Maslow, entertainment editorial assistant
