If you pack up the project files and host them, I'll help you cut them properly for looping. A lot of tracks seems to have a bit missing off the beginning, and others like INTRO1/2 are cut wrong.
Here's the tracks that need re-doing:
-GMINTRO1 and 2 (the end of 1 is put into the beginning of 2, you can probably just cut and paste it back over)
-GMINTER (The beginning is moved to the end, could probably just be re-cut)
-GMNEWMAR (Seems to have a lot missing, if you have a longer recording I could just re-cut it)
The following are fine but seem to have a tiny bit cut off the beginning:
-GMENBASE (very slight)
-GMINTRO3
-GMWIN (This isn't meant to loop so it doesn't really matter)
The rest are fine.
Lesson learned. Take a capture, SAVE the capture before processing, then process in a different project. I've cut and trimmed some of these up enough I don't think I have footage to easily re-cut them again.
The division between INTRO1 and INTRO2 seems totally arbitrary to me, and I'll gladly let someone else cut up that one. My GMINTRO3 was cut from this so I'm not sure how/if it's wrong, but feel free to re-cut as you see fit.
https://www.dropbox.com/s/rqsbwd8xgeoethb/GMINTRO_raw.7z -- I'm pretty sure I've already normalized that one, so just chop it up and export to OGGs.
GMINTER no longer has two complete loops to work with. It could be salvaged, but it's probably less work for me to just re-capture it and try my hand at cutting it again.
GMNEWMAR is fine and complete, as far as I can tell. It's the same length as the GUS soundtrack I'm using as reference, and listening to the raw recording it's only about a 30-second loop. If you're certain there's something wrong with it I'll give you the capture, but please check again as I'm pretty sure it's fine. Again I've only got my cut version, so I'll recapture this if you still think there's an issue with it.
I no longer have an uncut version of GMWIN. I'm not sure how I would've screwed that up, but that'll be easy enough to recapture. (I've got a savegame that's one turn from victory)
I'm also lacking an uncut version of GMENBASE. Yay for more recapturing.
