The Chrono Cross Original Soundtrack is a soundtrack of the music from Chrono Cross, composed by Yasunori Mitsuda. The soundtrack spans three discs and 67 tracks, covering a duration of 3 hours. It was published by DigiCube on December 18, 1999, and reprinted by Square Enix on June 29, 2005.
Xenogears contributor Tomohiko Kira played guitar on the beginning and ending themes. Noriko Mitose, selected for the role by Masato Kato, sang the ending song "Radical Dreamers ~ Unstolen Jewel ~". Ryo Yamazaki, a synthesizer programmer for Square Enix, helped Mitsuda transfer his ideas to the PlayStation's sound capabilities. The soundtrack has been described as having "some of the most haunting melodies known to man". The "Home World" tracks from the soundtrack have been termed "emotional", "driving" and "striking", while the "Another World" tracks are described as "slower", "dreamier", and more "serene" than their counterparts.
Note: this is the three-disc release of the Chrono Cross soundtrack, only released in Japan.
