beets: Some albums don't have an albumartist_sort

Problem

Running this command in verbose (-vv) mode gives:

[dorian@stonearch Sat May 13 ~]$ -> beet -vv info /media/windows/Users/Dorian/Musik/beets//250th\ Anniversary\ Edition\ Symphonies/03-19\ Les\ petits\ riens,\ KV\ 299b_\ XIII.\ Gavotte.mp3 user configuration: /home/dorian/.config/beets/config.yaml data directory: /home/dorian/.config/beets plugin paths: Sending event: pluginload library database: /media/windows/Users/Dorian/Musik/beets/library.db library directory: /media/windows/Users/Dorian/Musik/beets Sending event: library_opened /media/windows/Users/Dorian/Musik/beets//250th Anniversary Edition Symphonies/03-19 Les petits riens, KV 299b_ XIII.

Strangely, there is no albumartist_sort tag (even if there is an albumartist). This problem affects a few albums, but only a minority of my collection. Concerned albums are: https://musicbrainz.org/release/eea51aa8-bead-497a-8d22-5f4a20000b44 https://musicbrainz.org/release/cdb2a397-4684-4ff2-bfdd-3f8c2d95caa4 https://musicbrainz.org/release/eedbf924-14f2-4707-aeef-4e8856cb3ef0 among others. I can upload files upon request.

Setup

• OS: Arch Linux
