Confused by Tags

[simoncn]

Each tag value can only have one sort value. For this purpose, ALBUM=Anthology is a single tag value even though it might be applied to more than one album.

This restriction is clearly necessary for tag values that appear in indexTags (such as ARTIST and GENRE) as it would be very confusing for a tag value to appear multiple times in an index in different sort positions. The same restriction applies to ALBUM even though the situation is a bit different as an album name would normally appear only in the 'n albums' list and this list could contain albums with the same name in different sort positions.

You can solve this problem by using a slightly different configuration, as follows:

1) Set itemTags to: Artist Sort, Album Artist Sort, Album Sort, SortAlbum

2) Set tagValue to: Artist.value.sort={Artist Sort}, AlbumArtist.value.sort={Album Artist Sort}, SortAlbum.default={Album Sort, Album}

3) Set tagOptions to: Album.sortTags={SortAlbum, Artist}

This works by creating a "virtual tag" named SortAlbum for each file. The value of this tag is either the Album Sort value (if present) or the Album value otherwise. It also changes the sort order for the 'n albums' list to use SortAlbum and Artist tags instead of the default setting of using Album and Artist tags. The combination of these settings should sort your Anthology albums (and other similar cases) in the positions you expect.
