Being a fan game, Sonic Clash borrows music from other games, developed by companies involved in creating the game. As the game is a joint effort between SEGA and Konami, in association with Nintendo, Banpresto, Bandai Namco Games and Square-Enix, this game uses music from games such as: Final Fantasy, Star Fox, Castlevania and Super Robot Wars. Majority of the songs are from Sonic titles, though. The soundtrack spans 4 discs.
