It's an old album with DD tracks: http://vgmdb.net/album/11279

It has nothing to do with D2. Some tracks from D2 you can find here: http://www.kirillpokrovsky.com/

problem is... it missing many tracks and I have NO idea why. Many ppl asked LArian why, but got no answer. Kirill does not respond as well. The whole situation is just stupid.

And before you ask: no, you can't extract them from the game, it's encrypted. Yes, retarded politics, I agree.
