The Devil Children “Perfect Sound Tracks” is essentially an OST, though it includes two vocal tracks and the synth manipulation on the tracks sound of a slightly higher quality than the way they sound coming from a Game Boy. Note that this soundtrack is not representative of the 2002/2003 GBA Devil Children games, which were localized by Atlus USA. These are the Game Boy Color “Red and Black” titles, import-only.
Among SMT soundtracks, this one is far from noteworthy. Its arranged counterpart is worth listening to, but the OST has yet to leave a lasting impression on me. Part of the problem is the lack of looping. Many of these tracks are under a minute long (some under 30 seconds!). One is better off playing DemiKids to digest the music, instead of trying to get a feel for the music through this disc.
Or, you could just hunt down the arranged CD.
Whether you go for this album or the arranged album, both are printed by First Smile Entertainment, which has long been out of business. So, to all of you VGM fans hunting down this relic of the SMT music discography, I wish you luck on finding this one. I also wish you sympathy if you think you’re going to really enjoy this one. It’s nothing special.
