"Call Me Now" was a song composed by Daiki Kasho and performed by his band, Dakota Star, for Kaido Battle: Touge No Densetsu (also known as Kaido Racer 2 or Tokyo Xtreme Racer DRIFT 2). It was used in the intro of Kaido Battle: Touge No Densetsu: https://www.youtube.com/watch?v=xbZ80b_cBb4
Though no full version without sound effects can be found. The previous two Kaido Battle games (Kaido Battle: Nikko, Haruna, Rokko, Hakone and Kaido Battle 2: Chain Reaction) have full intro songs released, but Kaido Battle: Touge No Densetsu doesn't.
In November 2015, a user on GTPlanet by the name of Its No Use uploaded a midi version of the song and linked it to Newgrounds , which was written in his own style.
