Recently (in the past week or so) I’ve noticed that the individual track artists for albums have been partially or completely lost; this is most apparent on compilations with “Various Artists”.
I’m not sure if the format of upstream metadata has changed, resulting in some of the information being lost.
Example (on an album that previously had per-track artists):
MusicBrainz Release: Release “Relapse Sampler 2018” by Various Artists - MusicBrainz
All files have embedded MusicBrainz metadata.
In some cases I’ve seen albums where only most of the data is lost, e.g. only a handful of tracks still have their artist information.
Fix Match and Refresh Metadata via Plex Web did not fix the issue.
