I would appreciate a better handling of classical.
This means MB should be aware of the concept of a composition.
Basically this is the same as an album, a couple of tracks having the same value in a “composition” tag.
A "simple" solution would be that one can swap Album Name for “Composition” in Preference > Sorting/Grouping > Grouping
Switching album against composition might work in a few cases, but in practice would present other problems. (e.g. classical albums with an album title that has a certain added relevance)
I choose the following approach, which works nicely in a mixed classical/popular library:
I decided to use the similarity between classical composer in the past who created a 'work', with modern artists/bands who create 'albums'.
So I created a custom tag named 'Work', which I fill for obvious classical 'works'. (e.g. "Das Wohltemperierte Clavier", "Dido and Aeneas", etc.)
Then I have a virtual tag called 'Album/Work', which by default displays the album name, unless the custom tag 'Work' is populated, then it will show that.
A bigger challenge lies in the fact that of course a work will usually consist of more pieces. (movement, composition, part, etc.)
That will need some serious tweaking and advanced and consistent use of tagging and displaying options. (There are surely a few existing threads on that matter to be found on the forum)
If improvements to MusicBee were to be made concerning classical music, they would probably have to be in the area of levels of, and the displaying of groupings, or perhaps some smart algorithm for content dependent displaying/grouping of tracks/albums? (perhaps such as: IF 'genre category' = classical, then..., IF 'work' contains parts, then...)
One cause for this still being a challenge, is that there never seemed to be some practical consensus between bodies who might improve this a bit by setting some standard for this. But perhaps the likes of Apple, Musicbrainz, Discogs etc. have been making some progress here? (I haven't investigated this for a while)
