Plex Music Metadata Issues

In the past, I have posted on the forum hoping that there would be users who would be able to help me with questions I have about building and maintaining a Plex Media Server. The feedback is quite poor on here, but I won’t give up hoping someone can provide some feedback rather than nothing.

I am having issues with Plex Music and how it obtains metadata. I am not sure if Plex is in the middle of redoing the entire metadata platform or whatever you want to call it because Last.FM flat out fails and Plex as it has the ability to get rid of plugins should do away with Last.FM. Metadata never comes out the way it should and users have to spend hours of their spare time to get the library they went.

Just a reminder that no one who has paid even a monthly pass with Plex should experience these host of issues.

Can anyone provide feedback or confirm issues with Music Metadata on Plex? I am building a Premium Music Library on the NVIDIA Shield. All my music is overwhelming tagged well. If anyone needs information from me about my server or screenshots of how I have group agents, let me know.

Thank you in advance to any one who provides feedback.

The Premium Music library doesn’t use Last.fm, so I’m confused on that part. I have not seen reports of metadata being wrong, but there is an issue with posters I am looking into.

The premium music library uses Gracenote for deep music data such as mood and Plex Mix, but the artist information is Last.FM. There haven’t been reports because probably no one has reported them but I added music and I’m missing artist pictures, metadata on albums. My metadata is perfect. It used to work fine. I have no artist photos and certain albums don’t even fetch metadata even from Gracenote.

For as much money being paid and paid to Plex Pass for one of the prime features being a Plex Premium Music Library, look into:

There are APIs that can enrich Plex and Music a whole lot better.

Curious about this - I just added a 2TB Premium Music library, consisting of music with very well curated tags.

-I Selected the Prefer embedded tags option, and have Local Media assets at the top of the list
-All files have proper embedded cover art

I see some very odd behavior with Album art:
-Many multi-disc albums refuse to show their embedded cover art - instead plex shows a generic artist image
-Other artists that have 20 albums in my library show all appropriate embedded art
-…and yet other artists that have only 2 albums for example show one album correct, and the other using the generic artist image.

Any reason why it ignores the correct embedded metadata when told to? Is this related to your poster issue?

@anon18523487 -

As a Plex Team Member, it is your responsibility to look into behavior that was reported at least two weeks ago already. I can confirm the same that is happening with @linkj1 is happening with me.

At this time, there is a central problem with the Plex Media Server reading music as it ignores the correct embedded metadata. All files have proper embedded cover art as with the member. Did Plex do something recently with the reading of the metadata that something has changed. I’m not a technician so I’m not sure.

Please, will a Plex Team Member or Moderator attend to this problem with music scans please? If you need any additional information about the Plex Media Server, let me know.

Thank you.

I can confirm that I see this problem as well. My workflow is to use musicbrainz to ensure correct tags before I import music into Plex and I still see terrible results.

It is particularly bad with multi-disc albums. It spreads them across “different” albums and more often then not totally ignores disc order metadata. I’m pretty tired of having to correct everything manually especially when I know the original metadata is perfect.

I to am having issues. Compilation albums do not appear properly, Each artist appears as a separate album of the same name!. Please can you update us with a timescale to fix this functionality?

I think it is more important to maintain the current functionality than add new!

Same here. Loads of mismatches while my entire library is tagged to perfection.

Especially compilations are a nightmare to correct.

Aside from that not all tag fields are shown equally and mismatches are a-plenty.

When I get new music I’m forced to download everything, tag it, and then re-upload it.

Tagging is hardly new, basic players can do it - why not Plex?

If the Plex team is serious about betting on music this should be a priority.

I understand adding Tidal is good for monetization, the bills have to paid and it’s a great partnership for the casual listener already tied into Plex.

However, I use Plex Pass / Premium ML to escape the streaming services that randomly delete /replace songs from my playlists, grey them out when I go on holiday (Music companies still think in borders) or don’t have everything I want to hear.

Over the years I’ve curated a library I want to hear and maintain everywhere. If Plex Pass / Premium ML can’t deliver I’ll have to look somewhere else.

I am heartily glad to weigh in here. I have some suggestions for Plex, and suggestions to solve some of the problems people are having with multi-disk or especially multi-artist albums.

First, I confess I never used MusicBrainz. But I use MP3Tag. It can update tags as a batch process–select the files you want to re-tag, specify the tag(s) you want to change, and click the floppy-disk icon to save. But what you really need to know is that MP3Tag lets you set a number of tags that can solve the problems some people are having.

Understand this: the Artist tag is not the only tag you can use, or that Plex will recognize, for a recording artist. “Artist” means track artist, or the one who performed the music, or delivered the reading, of a particular track. In any compilation, use the “Album Artist” tag, and specify “Various Artists.” That way, Plex will index everything in one album, under an “artist” called Various Artists.

For non-compilation albums, Artist is the name of the artist and his band as the cover art lists them. Album Artist is how you would look up that artist in a record or CD store.

When Plex indexes everything, it lists each Artist with each track, and lists the Album Artist (if present) as the overall artist next to the album title.

Also–and very important for multi-disc albums: be sure to tag your tracks consecutively in an overall play order that goes across all your discs. Then select all tracks on each disk you have, and use the Discnumber tag to specify which disk held the track. Plex will then list all your tracks, grouped by disc.

With that said, Plex does not use all the tags that conform to the IDv3 standard. And it should! Specifically, Plex flat-out ignores the following tags, which a user or friend should be able to search on:

  • Composer
  • Movement (as “1st Movement”, “2nd Movement,” etc.)
  • Movement Name (as “Allegro”, “Allegro Vivace”, “Scherzo,” “Andante lamentoso,” or–in the case of a member of a suite–names like “Morning Mood” and “In the Hall of the Mountain King”)
  • Conductor

All that Plex uses are the tags Title, Artist, Album Artist (if specified), Album Name, Track Number, Disc Number (see above), Genre, and Year (of release).

To give you an example: say you have a track with Oscar Levant playing George Gershwin’s Rhapsody in Blue with the Philly Orchestra, Eugene Ormandy conducting. You would tag this (using MP3Tag) thus:

Composer = George Gershwin
Title = Rhapsody in Blue
Artist = Oscar Levant and the Philadelphia Orchestra
Conductor = Eugene Ormandy

Plex should then list this as:

George Gershwin: Rhapsody in Blue
Oscar Levant and the Philadelphia Orchestra, Eugene Ormandy conducting

The way Plex does things now, you have to write a ridiculously long title that would look like:

Tchaikovsky: Symphony No. 6 in B Minor (“Pathetique”), 3rd Movement: Allegro Vivace

and give the artist as

The Berlin Symphony Orchestra, Herbert von Karajan, conductor

Why not instead break things out using the Composer, Movement, Movement Name and Conductor tags?

(Frankly I would love to specify Soloist and Solo Role as separate tags. But that’s not according to IDv3 standard, and I’m not going to suggest that Plex break standard in this area.)

Therewith my suggestions, both as a new build and o solve a few immediate problems people are having (and that I once had!) with album organization and sortation.

I second this! My biggest problem is that Plex is still in the world of popular music. 'S’matter! Doesn’t anyone on the Plex team know that some of us have classical music in our libraries? And that we would like to tag these by Composer and Conductor and Movement and Movement Name, and have Plex properly recognize each tag? Imagine being able to search Plex for “all music by W. A. Mozart” or “all music conducted by Eugene Ormandy.” But today? Not a chance.

Because Plex uses only the tags Artist, Album Artist (if you can use a good tag editor that can specify it), Title, Album Name, Track Number, Genre, Year (of release), Discnumber, and Cover Art. (That’s a nifty one. I’ve started tagging my new rips and LP digitizations with the cover art. It saves me trying to find and upload cover art! Better yet, smartphone apps like Android Music or Samsung Music can show the cover art easily.)

Come on, Plex. How difficult would it be to recognize Composer, Conductor, Movement, and Movement Name when specified? All of us classical library curators would be eternally grateful.

In my experience, pulling metadata for music artists and albums is a buggy mess. The Plex Dance ™ doesn’t work and it shouldn’t even be a thing that exists.

I’ve seen instances of my Plex server going into a CPU usage death spiral whilst at that time the Plex web UI reporting that there is no activity on the Plex server. I’ve also seen instances of attempts to pull metadata for music artists and albums fail / seemingly do nothing and then following a Plex server restart, that same metadata pull operation working as expected with absolutely nothing having been touched in my music collection file system or mp3 file ID3 tags.

It’s a mess. I want to like Plex, it does have a lot going for it and I’d be inclined to sign up for a Plex pass if it wasn’t such a mess of bugs.

I’m going to have to add my complaints too. I’m pretty ■■■■ about tagging my music. My music does not get added to my collection until I personally verify each tag. I make sure the song title, track number, year, genre, artist, album artist, disc number (when necessary), album title and tagged. I also make sure that each track has album art attached to it. Once I save I move it to the folder where I keep my PLEX library. Lots of times it won’t read the tags and will show a generic band photo or just nothing at all. Other times it’ll read the song title as “01 Song title”. This is very aggravating. I do have PLEX set to read tags first before using Gracenote.

I’ll add to the list here with my own complaint about the metadata issues with my Plex music library. I have had a great experience with my TV and Movies libraries getting metadata correctly so I decided to take the plunge and move from iTunes to Plex for my music as well. What a poop show… so many mismatches and missing metadata for things I have had properly tagged in iTunes for years. Plex simply won’t match the Artist/Album with what it’s finding in Last.fm even when I try to “fix match” and pick the right thing - still won’t match up, download metadate, attach cover art, etc. I have tried over and over again to match up individual artists or albums but as I said it still doesn’t work. Now that I read this thread, I see it’s a common problem and not just me. No bueno, please fix Plex Team.

I think I may be having the same, or similar problem.

My embedded tags are in excellent shape, and Plex is configured to use them. I also have artist and image files stored locally. Plex seems to be using my album cover images, but it is not using locally-stored artist images, and there are so many mistakes in the library that I have to believe Plex isn’t using embedded tags either.
