"Are you familiar with Mr. Bill?"
I am not, but I've seen similar. I just don't get this concept...
"in more experimental music and genres like low-fi, you are not looking for realism"
RealTracks are about realism smile

If I would be in search for realistic audio loops - that I can make sound unrealistic... It still would make sense to go to Mothership-BIAB and generate something that is useful for a particular composition, instead of using short pre-made snippets.

What I think can be useful for loop/section based DAWs is this: If you get your section way you want it in Trackview (or audio edit, etc.)... select a part and drag it directly to DAW. So instead of the whole track, only selected area will be dragged. That actually would be a neat item for wishlist, perhaps not too hard to implement, and can be useful for other things too, not just for loops.
