22. DNCE, "Cake by the Ocean"
My favorite scene in the Mike Love autobiography is when he goes deep on his creative process during the composition of "California Girls." "So I wrote, 'The East Coast girls are cool.' No. 'The East Coast girls are sharp.' Not quite. Then: 'Well, East Coast girls are hip.'" Eureka! I think DNCE put similar cerebral ministrations into this beach-blanket hit, where the Joest of Bros writes a song that's basically a Weird Al parody of itself.
