SPF your boomboxes and polish up your Ray-Ban game, kiddos—’tis the season of the summer jam.

Every year, a clutch of eager contenders run the gauntlet, but only a lucky handful make it all the way to beach blanket babylon; in 2009, those honors went to the likes of Kid Cudi, Phoenix, and Keri Hilson.

Today, Santa Barbara native Perry makes a naked grab for this year’s seasonal-champ ring, strapping on her rollerskates for a Jeep-bumping neon-pop ode to the popsicle-maiming bikini vixens of the Golden State, “California Gurls.”

Stream the song—it’s the first, Snoop Dogg-assisted single off her upcoming still-untitled album—here at her official website and tell us: Top of the pops by June, or out with the old Memorial Day BBQ coal? Who else will own this summer’s airwaves?
