To the Edge
From Nookipedia, the Animal Crossing wiki
To the Edge is a song that first appeared in Animal Crossing: amiibo Festival. It is one of the three songs in Animal Crossing: amiibo Festival, Template:AF+ and Animal Crossing that the K.K. Slider plays whenever the player requests an invalid song. The song can be described as someone literally going "to the edge" of sanity or "to the edge" of a cliff, but not fall off. It is a very laid-back song that has a horn playing, simple R and B drums, etc. Sometimes, you hear K.K. Slider whistling. Jakoten, Wart Jr., Clara, Megumi, Prince and Tabby play this song if they have a stereo in their house.
