Go K.K Rider is one of the many songs that you will hear in Super Smash Bros. Brawl originally from the Animal Crossing series. It's said to play in Smashville, but if this music only plays at 8:00 PM on a Saturday (when K.K Slider plays a song) or if it's the whole time on the stage is Unknown. K.K Slider is known as the creator of the song (of course, however this is a remix) and appearantly this song makes Sakurai think of heroes arriving late, this may be hint to the game, but nothing has been found to this affect.
