I really wish I could help you out. :( I really like Great Orchestral Game Soundtracks...
It says right here that the Collector's Edition came WITH an Official Soundtrack for the Game:
CollectorsEdition.org � The Dark Eye: Demonicon Collectors Edition (PC) [DVD-ROM] (
http://collectorsedition.org/game-db/the-dark-eye-demonicon-collectors-edition-pc-dvd-rom)
What's even worser is the fact that I can't seem to find a Online store that specifically says that the purchase comes WITH the CD Soundtrack... :( Please help me out, so, that I can help YOU out. ;) Might you know of a store that sells the Collector's Edition? =O
EDIT: Some guy has uploaded the first song from the Disc to YouTube, have a listen to it. Maan...it REALLY is a Great Orchestral Game Soundtrack!!! xD Soo, I went ahead and PMed him/her to upload the entire Soundtrack to MediaFire. ;)
