As long as the nfo implementation is dependant on folder structure, there is nothing you can do on your end with nfo's.

One choice is to upload the artist information to http://www.onlinemusicdatabase.com/ and scrape it from there.

Another would be to use the XML library approach linked to in my post above. Generally, export the music library, edit the file with your information, and import it back into Kodi.

The endless loop thing is still a bug, IMO. I think, if I recall, I have to pull out my keyboard and hit ESC to get out of it.
