I've got one: https://drive.google.com/file/d/1U6DF4yPFbvl2S3VLHwksQdld5zI7YzbZ/view?usp=sharing
If anyone wants to make a plugin using these to play in Marathon 1, by all means do so. I love them just as much as the original Quicktime tracks and their remixes (one on modern quicktime MIDI too!). I only wish there was a CD track for all of them instead of just 7 though, so the missing tracks in such a plugin may need to use either Craig's remixes or the Eupfhoria album ones (with their respective owner's permission of course).
If not a plugin, there's always implementing them manually by changing their names to match the track numbers. They're in MP3 format however so if you want them in OGG format, just ask and I'll convert them to OGG as well.
I'll admit, I cheated and ripped the youtube videos of the tracks, but that's because Marathon 1 CD is abandonware now and I my Mac doesn't have an OS that can run it. (Not to mention I prefer the Aleph One version, thanks to quality of life improvements and it works on both Windows and OSX)
