To the Edge is a song by K.K. Slider. 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.
These villagers play Hypno K.K. inside of their homes once they own a stereo.
