Well, that a difficult thing. The music on the CD was based on Jochen''s compositions and performed partly by him and a bunch of the studio people. Thalion doesn''t exist anymore, so I''m not sure if someone still has a copyright to that stuff.
One thing''s sure: Jochen wouldn''t have anything against posting the MP3s. And I consider the risk of somebody''s popping up with copyright complaints very, very small. I''d say: Just go ahead!
