A candy voice and colourful production are the only givens in this SoCal pop queen's oeuvre, where playfulness abounds across genres. In hipster-dissing trip-hop provocations ("Ur So Gay"), synthy anthems for the nouveau riche ("This Is How We Do"), and innuendo-rich afterhours EDM ("Bon Appétit"), Katy Perry flexes her whimsy. The same ebullience that makes the frat-tastic "Starstrukk" a goofy gem fuels a search for fairy-tale love in "Not Like the Movies."
