At first the situation with the soundtrack CD might seem worse than the multiple DVD versions.
In fact, it’s much simpler – every CD version has the same 14 tracks, plus bonus PC content in the form of the now defunct Avalon web site.
Catalogue numbers include
- Media Factory (Japan) ZMCZ 1171
- Sonmay (Taiwan) SMA 059
Note: The Sonmay CD is now known to be a pirate edition. See http://www.digital.anime.org.uk/piratefaq.html for more information
