K.K. Salsa
From Nookipedia, the Animal Crossing wiki
K.K. Salsa is a K.K. song that is very upbeat and funky Cuban-themed. It has the traditional salsa Wurlitzer, which is an electronic organ; it starts out as the melody then turns into background music. It has conga and bongo that sounds like kitchen utensils being beat on. It also incorporates shakers, electric bass, and the synthesizer that gets the main melody later in the song. Peanut, Spork, Lily, Miranda, Bessie, and Champ have this song playing in their houses.
