setting ignore.sort in the All Artists tag?

[simoncn]

As you have discovered, the All Artists index shows all Artist tags in your library. To change the sort order for these Artist tags, you need to set Artist.ignore.sort={The}. This also changes the sort order for Artist tags shown in the Artist index. For AbumArtist tags that are shown in the Artist index or the AlbumArtist index, the equivalent setting is AlbumArtist.ignore.sort={The}.

The Artist index works as it does because many users want to see an index of "main artists." For large classical or jazz libraries, many tracks could have multiple Artist tags for "supporting artists" and putting all these artist names in the Artist index would create a very large list of minor artists that would make the index harder to navigate. Tagging an album like this with an AlbumArtist tag for the main artist excludes supporting artists for that album from the Artist index. To include supporting artists for the album in the Artist index, the AlbumArtist tag can be omitted.
