This is the soundtrack for the PS3 game "Mugen Kairou: Hikari to Kage no Hako" (Infinite Corridor: Box of Light and Shadow). It's a rare game soundtrack that features only one very long piece of background music. The music is a masterpiece, using one measure to represent a year, expressing life through music. I'm selling it because I haven't used it in a while. I've played it several times. There are no issues with the functionality. The case is cracked, but the CD inside is in good condition. I'm sorry, but I cannot negotiate on the price. Please feel free to comment if you have any questions. Thank you very much.
