Well, I've read about a pack of mp3's that have a HQ version of the musicthemes of the game. Unfortunately every link I found was broken...

Anyone has them?

The only pack I know of is the official 320 kbps soundtrack available for purchase from Jeremy Soule's (the composer's) site, http://www.directsong.com

Any other "pack" going around is likely unauthorized, I'm guessing. I purchased the soundtrack from DirectSong and I can tell you that it is high quality and includes a reimagined bonus theme track.
