Since I got some spare time last night, I managed to arrange a tracklist prototype. Tracks in red are from the OST, tracks in gray are the Promos.

The promo cues had tricky titles, but I managed to find them all on the series. Some tracks are marked with an asterisk, because I didn't bother to compare them in detail with their corresponding episodes (assuming that their titles are correct). I blatantly gave up with 'The Rising Tide' since I couldn't remember any of that material aside of the final minute, so I just put it in the end. Perhaps somebody else knows better, but I hope this serves as a backbone to get most tracks in place.
Thanks so much for your work on this, AdrFax - any chance someone could upload this as an expanded edit?
