K.K. Soul
From Nookipedia, the Animal Crossing wiki
K.K. Soul is a K.K. Slider song. It is very contempt with intricate drum beats, melodies, and is not as soulful as you think it would be. It is more of a stepping-out, urban, or gleaming theme that is happy. It is also a very homey song and may sometimes get confused with Soulful K.K.. Chadder, Henry, Mint, and Daisy will play this song in their homes.
