Sorry if I’m stating the obvious, but just in case:
The MusicBrainz database is usually used in conjunction with other programs and/or taggers to organize collections.
- The “official” MusicBrainz tagger is MusicBrainz Picard.
- I believe that for classical music the “Classical Extras 2.0” plugin is used almost universally, for a massive amount of tagging flexibility
- After tagging, you will want a music player that can effectively display and sort, and possibly make playlists etc, with these tags. Here is an example tutorial of how to do so with the MusicBee player.
