Words and music by Katy Perry, Mikkel Eriksen, Tor Erik Hermansen, Sandy Wilhelm, and Ester Dean / arr. Alan Billingsley
Katy Perry's No. 1 single from her album Teenage Dream lifts you up from beginning to end. It speaks of people that are full of life and fire inside---and make you go "Ah!" Perfect for year-end concerts, too.
