 The soundtrack was produced alongside the game by Shinji Hosoe , with contributions from Nobuyoshi Sano and Ayako Saso , as the development team didn 't have enough time to produce them separately . The team did not initially plan to have music , but ended up producing techno , which Tanaka believed helped players to enjoy a fun feeling while playing . Hiroshi Okubo believed techno would give a feeling of energy , journey , and speed , and commented that the genre was chosen because it embodied the game 's " unrealistic speed and tension " . This was commemorated by the release of Namco Game Sound Express Vol . 11 , which featured remixed versions , on 21 January 1994 in Japan .
