And frankly, it’s hardly different from creating a new release to capture a digital release whose tracklist is changed:
The example given was Release group “W A R E Z” by MASTER BOOT RECORD - MusicBrainz - an example I’d give is Release group “DanceDanceRevolution SuperNOVA ORIGINAL SOUNDTRACK” by Various Artists - MusicBrainz where I’ve filled in the disambiguations.
I’d only been adding the new tracks to reduce duplication, but I guess to really be “correct”, we need to introduce even more duplication into the database.
