K.K. Ska
From Nookipedia, the Animal Crossing wiki
K.K. Ska is a K.K. Slider song. It is Jamaican and fast-paced with a strong off-beat part at the end before it repeats. It is a short song and a forerunner of K.K. Reggae. It has a horn section, simple funk drums, an R&B bass, and riffs the whole way through. Bluebear, Bud, and Ruby play this song in their houses.
