"oh, i'll just load this folder into musicbrainz picard so i can see if i can find the rouge id3v2 tag that's causing anything tagged with Various Artists to show up as one random artist in plex"
this folder has approximately 20,000 files in it
and something about macos makes it extra slow at working with my NAS
so yeah, 27 days to apparently process less than a third
(i'm sure it'll speed up once it actually starts processing them, but still)
