Plex is badly mangling import of a Music library

[pshanew]

As far as I know, the Plex Dance shouldn’t be required any longer when using Plex Music/Plex Music as the agent/scanner. However, it might be worth a shot:

The Plex Dance ™

The purpose of this is to remove all cached metadata and xml data for an item that Plex usually keeps. This helps when you want to “start from scratch” for particular item move all files for the media item out of the directory your Library is looking at, so Plex will not “see” it anymore scan the library library (to detect changes) empty trash clean bundles (in menu next to server name, when accessed under ‘More’) double check naming schema and move files back scan the library Support articl…

You might also try un-matching the artist and then re-scanning/matching to force the issue.
