Un-matching Mismatched Items - Album Art - Must this be done on an item by item basis?

Plex Media Server Metadata & Adding Files

Server Version#: Version 1.23.6.4810
Player Version#: Version 4.61.2

Is there a way to “group” items to unmatch them at the same time? I have a collection which has a number of items/mixes that I have prepared, and tagged, and are not “matchable” to any data base. Plex attempts to match these and frequently the matching is erroneous. To unmatch all of the mis matches I need to individually unmatch all such items. Would be easier if I could highlight all these items and simply “unmatch”. I may be missing it but cannot seem to find this. These are music files (running Plex Music as Scanner and Agent, and Album Art as Local Files Only) and Agents have Local Media Assets at top of list. Thank you.

While you can select several items in a library and perform some operation on the selected items at the same time. (e.g. adding to a playlist)

Unfortunately, matching/unmatching is not among those actions.

@OttoKerner - thank you - thought that might be the case. Is there any way after manually unmatching to prevent improper rematching? Think I know the answer to this as well. Thanks

As long as you use the “Plex Music” agent for your library, rematches should not occur, after you have explicitly unmatched an item.

I recommend you to stick to this folder and file organization, though:

/Music
   /Album Artist
      /Album Title
         01 - Artist - Track.mp3
         02 - Artist - Track.mp3
         03 - Artist - Track.mp3
         ...

And make sure to use a file format from which Plex can read embedded meta tags.
(i.e. WAV and MKA: no, but Flac and mp3: yes)
It helps immensely if those meta tags are complete and don’t contradict the folder organization.

Thanks - all tags are organized as described in FLAC. I will manually unmatch the items (there are approx. 1000) and, using Plex Music as my scanner this sounds like it should work. Unfortunately same issue across a few PMS I have set up…Thanks for the quick reply.

If you have many unmatchable items, you want to enable ‘Prefer local metadata’.
But doing so requires you to stick even closer to the above mentioned folder organization, or the result might be chaotic.

Thank you again - “Prefer Local Metadata” is enabled. It is looking like your solution of force (i.e manual) unmatching each item, and having Plex Music as agent (and the other settings described in this trail) in fact works to retain the native album art metadata where matching is incorrect. So, thank you @OttoKerner

Scanning my library today it seems as if some items have re-matched - even after forcing unmatch manually. Not nearly as many as last time around, but many nonetheless.

Issue is persisting, although not on the scale it was previously after using settings described by @OttoKerner. It also seems as if each time I review the libraries, it is not the same artwork effected but different entries each time. Curious whether other users are experiencing this erroneously “re-matching” that overrides “local” preferences.

Update - this issue persists only on PMS run on Windows. The PMS running on MacBook Pro has preserved the correct artwork/posters after force unmatch.

11

@OttoKerner - is there any possibility of a “group unmatch” functionality to be introduced? Ongoing issues with re matching after forced unmatch to correct album artwork. Thanks

@OttoKerner I am able to report with some certainty that using Plex Music agent, rematches are occurring requiring manual unmatching, again, daily (or following a scan). Hence a request for a group unmatch function until there is greater stability

For what it’s worth for me, this continues to work to retain custom album art.
