Larian Studios, the creator of Divine Divinity, has released a 30mb 'christmas gift' containing eleven original music tracks from their game Divine Divinity, including some songs which aren't present in the game, all composed by Kirill Pokrovsky. If you've read my review of the game, you'd know that I feel that the music is pretty good, so I recommend downloading the pack from here.

You can also get some tracks in mp3 format from the official
Divine Divinity website.

Thanks for the tip, Vasikka.
