Wandering
From Nookipedia, the Animal Crossing wiki
Wandering is a song played by K.K. Slider, and can be put onto a music player. It has a happy tune with some minor scale notes and the theme is like one are wandering around with no particular place one is intending on being at (hence its name). It has a first verse, then goes on to the chorus. After that, it goes on to the second verse that sounds much like the first verse, then repeats.
