TL;DR: When adding an artist that is not known to the plex library metadata source it “guesses” the closest option overwriting the manually entered artist information.
I was adding some music from UwU Underground into my library, it was originally identified as “Various Artists” and “[Unknown Album]”. After correcting this to the correct values the album was kept but the artist was over written by plex to “Digital Underground” whom I already had in my library.
I added UwU Underground as an artist and the album to musicbrainz less than an hour before adding to plex. So I expect that the metadata source hadn’t picked it up yet
I have the library configured to use the Plex Music scanner & agent with “Prefer local metadata” enabled.
I think you’re slightly missing the issue I’m asking about.
If I manually change the album artist to UwU Underground, Plex is ignoring this and changing it to Digital Underground a completely different artist.
