Surfin' K.K.
From Nookipedia, the Animal Crossing wiki
"Surfin' K.K." (エレキそんぐ, Elec Song) is a K.K. Slider song that makes you feel like you are on a surfer's paradise: a beach on a really hot day (hence its name). It incorporates an R and B bass, an electric slapped guitar, and a drum kit hitting the cymbal many times. Alice, Spike, Katt, Renée, and Static plays this song in their houses.
