Only match if matches to MusicBrainz release
If we are an editor of MusicBrainz the Only match if matches to MusicBrainz release option maybe useful. When this is enabled Auto correct from Discogs will only try to match to Discogs if the song has a MusicBrainz Id, and will only accept the match if the Discogs metadata is a good match with the existing MusicBrainz metadata.
