You don't know who Kazumi Totaka is? well, he's the father of Nintendo's most furry beloved sounds: Yoshi's both SFXs, Yoshi Story's soundtrack, The Lylat language from StarFox and StarFox 64, even the music from Animal Crossing (in fact, he depicts himself as Totakeke, AKA K.K. Slider). His most known work is the animalese language, which also appears in the Pokémon Gen III games as a hidden character. This song is hidden in maaaany games where Totaka worked on (Yoshi's Story, Mario Paint, Legend of Zelda DX, Luigi's Mansion, Pikmin 2... and so on)

If you want this song's real form on Animal Crossing, it's easy:
Go on Saturdays from 8 PM to 12 PM to the Roster and when K.K. Slider asks you for the song, type "K.K. Song". Then sit at the chair on the back and... well... just listen to it.
