Composer list in library browser

[TheOldPresbyope]

I've only seen the Name tag in radio streams but never in song files so possibly it could be used to store the Composition text. MPD already supports the rest of the tags in your list.

1) What is the hierarchy that determines which columns appear on the panel?

Genre
- Composer
-- Composition
---- Title


2) Are Performer and Album attributes of the Title or part of the hierarchy?

----Title
----"Album"
----"Performer"

...

As well as I know, there is no one standard in classical collection organisation. In my case, the collection is organised by:
- Epoque. There is no support for this tag in MPD so probably it will not be used, but it should be replaced by the Genre EDIT: By Genrea, I mean of course the subgenres of Classical, ie: Opera, Concerto, Vocal and so on.
- Composer
- Composition
- Performer (Artist in my case)
- Album

...
Concerning the search. I'd like to have possibility to search by:
- composer
- composition
- genre
- performer
- album

...

Seems like reasonable way to organize the collection, but MPD still not seeing the Name tag in the sample mp3's that you provided. The tag is in the file according to Mediainfo dump so more investigation required...

This arrangement is certainly worth trying.

I took a random walk through the MPD sources. I decided I don't have the chops to trace the logic through all those interlocking C++ modules.

Now that I've got a stable full of tag editors I can try to create variously tagged MP3 files to do black-box testing of MPD's parsing skills.

Oh, my, the ID3v2 tagging scheme is nothing like I expected. 

The metadata is carried in a series of frames. From the ID3 tag version 2.3.0 document on the ID3 website, "[T]he text information frames are the most important frames, containing information like artist, album and more." 

Each text information frame has an 4-character identifier beginning with "T". What my tag editors call the "Title" tag is actually a frame with the identifier "TIT2"; "Artist", the identifier "TPE1";  etc. The descriptions of these pre-defined identifiers in the ID3 tag version 2.3.0 document are only suggestive of these specific interpretations.

There is no obvious pre-defined T-identifier for "Name". Perhaps "TIT1", which is defined as "Content Group Description", would do, but I couldn't find it offered by my editors. YMMV.

When I used any of several tag editors to add a "Name" tag to an existing mp3 file, it was entered into the file as a frame with identifier "TXXX" (defined as "User defined text information frame") which contains the name "Name" and the value I entered in the tagger. (Same for tags I named "NAME" and "name".)

MPD plays the file but doesn't display my added tag, no matter the capitalization I used. I can only surmise that MPD has a table of the pre-defined T-identifiers it recognizes and doesn't trace through TXXX's  to pick up user-defined values.

I haven't looked into genre tagging in ID3v2 yet.

FLAC with its use of Vorbis comments is looking better and better to me.
