Followed the instructions on the blog post (https://www.plex.tv/en-gb/blog/find-that-tune/) and updated my Music library to get the new swanky metadata…

And it’s completely broken loads of albums in my Library.
I tweeted about this earlier but seriously Plex. I love you, I really do - but stuff like this - where you’ve lost loads of my data and know I expect I’ll need to re-make my library, this just pushes me towards Spotify and Apple Music.

Anyone have any suggestions before I implode inwardly?

How many copies of the album do you have?
Click on the vertical ellipsis ⋮ at the end of each of the copies of e.g. Lords of Summer and compare the folder path and the file names.
Are they identical or different?

Thanks I should’ve posted the obvious difference in tracks. The album is a three disc album. And the metadata has been incorrectly identified for each track despite for example the first three tracks that have all been indentified as being Lords of Summer being different files with different lengths etc.

As you can see the first track is even explicitly named ‘Hardwired’ (which is the name of the first track on the album but Plex has identified it completely incorrectly.

I assume my previous personally input metadata is lost?

Did you edit the metadata in Plex? If so, that’s very unfortunate.

You should always write the metadata into the files themselves. So they are safe when the media server or player software blows up.
I recommend to use the ‘edit’ function in Plex only for minor corrections.

I do have the data in the local files. I write the ID3s using a separate tool.
EDIT: I write the data into the ID3s after/during ripping the MP3s from CDs.

That’s good then.

  1. Edit your music library,
    go to the ‘Advanced’ tab. Is ‘prefer local metadata’ activated? (DON’T change it yet.)
  2. Can you give me an overview of how the files are tagged? Similar to
    mp3tag_multidisc_album
    mp3tag_multidisc_album1717×741 53.6 KB
  3. Take a look at the Plex XML info of the first track. Can you copy the contents of the guid="...", parentGuid="..." and grandparentGuid="..." into here please?

  1. I had already tried changing it back to ‘prefer local metadata’ in an attempt to fix it :frowning:

  2. I just grabbed Hardwired album from the Plex server and here is how it appears it MP3Tag:

    Seems the data is still there!

  3. guid=“com.plexapp.agents.none://34746/1?lang=xn” parentGuid=“com.plexapp.agents.none://34746?lang=xn” grandparentGuid=“com.plexapp.agents.none://34587?lang=xn”

Hm, this means the album was not matched previously and is now still clinging to the old, now partly defunct music agent.

Just as an experiment, perform the Plex Dance “light” (omit step 4) with this one album.

Yeah I did it with the whole library actually and no change. It’s still messed up.

What was most suspicious was that even when I moved the folder away - music wouldn’t play anymore obviously, I then re-scanned the files, cleaned the bundles…
Even at this point it showed my music still in the library with all of the art and everything when I thought it would figure out that the music had gone?

So no change after I put the files back and rescanned again.

Edit your library,
go to the ‘Add Folders’ tab
verify that every folder path in there is:

  • still in existence
  • accessible to the server
  • not completely empty

Yep it’s all good…

Verify your main database file is in good health.

  1. activate debug logging (not ‘verbose’!)
  2. quit Plex Server
  3. wait 1 minute
  4. start Plex Server
  5. wait 5 minutes
  6. fetch log files and attach them here

Or inspect them yourself. Take a look at the Plex Media Server.log file and seek for messages about database corrupt or malformed.
If you find these, you may have to repair your database.

And standard question for Synology user: Have you done the changes described in here?
