I was asked for a re-up, and I noticed there have been made additions to the track list (not sure whether they are later additions to the game itself, or just a better job at compiling the score on the part of a YouTuber). So I checked different score playlists on YouTube, and since I failed to download the longest list of 122 files, I went for this list with 98 files:

I failed to download the long track near the end, which is actually a compilation of campaign tracks. So, I ended up with a 97 track score. Too bad no "official, proper" source has released a COMPLETE soundtrack which would have made these fumbling compilation jobs obsolete.
