Katy Perry's "Firework" & Other Songs of Empowerment

The exuberant smash hit “Firework” celebrates nonconformity in all its beauty, and this playlist lets that flag fly high. The sheer power of the assembled artists is a call to arms, whether you identify with Destiny's Child's meteoric narrative of beating the odds, “Survivor,” or Madonna's poppy classic “Express Yourself,” a rousing credo from an artist who knows a thing or two about calling the shots.
