Not entirely legal? Well the guideline on the other forum I'm a member of is if the soundtrack is not reasonably available for purchase, it's okay. In the case of Kirill Pokrovsky's music, he lets people download it for free from his site, so on balance, I'd say it's probably fine. But whatever, link removed anyway.

If you want more tracks released, e-mail Larian or Mr. Pokrovsky yourself and ask.
