“What’s New, Scooby-Doo?” is the upbeat, pop-punk theme song performed by the Canadian rock band Simple Plan for the 2002 animated series of the same name. Co-written by Rich Dickerson and Gigi Meroni, the catchy track perfectly captured the modernized, energetic vibe of the franchise’s 21st-century revival and has since become an iconic piece of pop-culture nostalgia. #simpleplan #scoobydoo #shaggy #punk #poppunk
