K.K. Slider is based on the game's sound designer Kazumi Totaka. K.K. Slider's Japanese name "Totakeke" is taken from the fact that in Japan, last names are written first, so it would be Totaka Kazumi. That can be shortened to "Totaka K" very similar to "Totakeke". Totaka has also hidden music in every Animal Crossing game, and at least twelve other games. People now search for the hidden music in his games, which is known as "Totaka's Song".
