Alright cool, I'll try to keep it all spaced out, wouldn't want to overwhelm you. Let's see about getting some Devil May Cry 5 OST converted then...
Voltaic Black Knight:

somewhere around the 2:30 mark is the loop point and goes back around to the 0:50ish mark.
Devil Trigger:

Not sure how you'd turn this into a good loop without making it a complete end to start, I dunno really. Could try experimenting around.
Bury The Light:

The ending of this song is actually the same as the intro so that works out well.
The Duel:

You can copy the loop this guy made which is around ~0:33 and 3:20 or so.
Silver Bullet:

Excuse the absurd extension time, this was the only version I could find with the full violin intro.
Loops from around 4:33 back to ~1:54 or so.
Thanks by the way for taking the time to do this. Oh and another thing, not sure if you're aware of this but a working archive of the old brstm site is up.

They even got some new additions added in, maybe you can see about getting your loops uploaded onto there?
