Composed by Shoji Meguro, the "rare soundtrack" is 45 minutes in length and was included in the five-disc "Nocturne Sound Collection" box set published in Japan in December. Additional music for the role-playing game is by Atlus sound team members Kenichi Tsuchiya and Toshiko Tasaki. Arrangements of themes from Shin Megami Tensei are composed by Tsukasa Masuko.
The Nocturne Sound Collection five-disc box set is available for shipping from CDJapan, featuring the PlayStation 2 edition music scores and piano arrangements by Duke of Pianeet.
