Plex removed artist from my music library after I added "Poster Art"

I added poster art to a music artist in Plex. Plex scanned it and removed it. I can’t find it since the trash was set to auto delete. Now, the artist is still in my file folder and safe, But Plex will not add it back into the library. I am at a loss.

Who was the artist so I know what to look for?

Bush, and LISA.

Your logs indicate PMS is having trouble reading the image file. Can you post a zip of the poster so I can try. Don’t post as a regular image file, the forum might modify it. Or upload to cloud and provide a link.

That’s going to be tough since I pulled the image off Google, and I don’t know exactly which picture I used. I didn’t save the image into the file folder of the artist. I just saved it to the desktop and then uploaded it to Plex. Then, I deleted the picture immediately.

Oh, I wonder if Plex didn’t copy the image over fast enough before you deleted it. Try again with any image, but wait to delete the file until after the scan is complete.

Are we trying to recreate the issue? Because I have done it this way for most of my library without issue.

I’m trying to actually avoid the issue by setting is this is a timing issue. The scanner may have changed and can’t keep up with your routine.

No problem. I will add the poster and then sync the library, before I delete the pic going forward. Now how do I get Plex to recognize the artists it deleted? They are still in the main folder I have Plex pointed too. But Plex refuses to add them back in.

Have you looked under various artist?

I don’t recognize these names, but they sound like two distinct artists. That would make the release (i.e. album) a “collaboration”.
Plex doesn’t handle collaborations. If even one of the involved artists is also active solo, chances are that the release is merged into the albums of that solo artist.
If you’re particularly unlucky, all albums by that artist will have their artist renamed to bear the artist name of the collaboration release.

I have; they are not there.

It’s strange that the artists were there for months, until I added the new poster art. Then plex removed them.

Also, they are two separate artist. Bush is from the 90’s, and LISA is more current. They have never collaborated.

So you are talking about two different releases?

  1. have you “Prefer local metatags” enabled? (don’t change it yet!)
  2. which file format is used by your audio files?
  3. are these files tagged with all relevant information? (embedded meta tags)
  4. are your files organized in this folder structure? https://support.plex.tv/articles/200265296-adding-music-media-from-folders/

They are two different “bands”. Completely different genres with completely different albums.

  1. Not sure where that option is located. So, I assume no, since I haven’t changed anything.

  2. FLAC Audio

  3. Not sure how to check for that information?

  4. Yes, this is the structure, E:\Andy\Music\PLEX Flac Music\Bush

It’s in the properties of your music library in Plex, on the Advanced tab. https://support.plex.tv/articles/200289266-editing-libraries/

I recommend mp3tag
(the file properties tab in Windows file explorer is inadequate)

This is missing the “release” folder level.
There are no single tracks in Plex. Every track must be a part of a release (i.e. album, single, EP, etc.)
So they must be tagged with an Album Title metatag and be stored within the dedicated folder of that album/release.

Be particularly careful with the “Artist” tagging:
There are separate tags for [track] Artist and AlbumArtist.
While [track] Artist can be different on every track of a release,
AlbumArtist must be identical for all tracks within a release.
The artist folder in your file system must follow the AlbumArtist tag.

I haven’t changed any of those settings.

It appears all of the relevant Metadata is correct. I used the MP3tag, and everything is correct.

I apologize, the folder structure continues with the correct, Artist/Album/Song. I just stopped at the artist level. But it does have all the relevant information.

Why are you using Personal Media Artists?

I have never changed any settings. So, if there is a setting I need to change, please tell me.
