I woke up this morning and hundreds of my 14k+ music tracks suddenly have no title. And some of the albums are seriously messed-up! Take a look at the image of They Yellow Submarine below. No album art… Disc 13??? The only way I have found to fix this problem is to Unmatch and then Match every single affected album.
Even some “albums” that I have created manually and hand-entered all the information are now missing titles that I had previously typed in.
This could take dozens of hours to fix manually! Is this a known issue? Is there some less time-consuming way to fix the problem?
The library was a former Premium Music library, right?
It still has references to Gracenote, which is no longer available as a datasource to Plex.
Do your files have (correct) embedded meta data?
When you edit this library, and go to the ‘Advanced’ tab, what are the Agent and Scanner selectors set to?
Thanks for your response. I don’t exactly know what a “Premium Music” library is, but I assume you are correct. I have been growing and tweaking this Plex music library for about 5 years.
I expect that the vast majority of my files have correct embedded meta data, but I’m sure that many of them don’t. If I had to guess, I’d say that maybe 13k have correct meta-data and 1k don’t. Just a rough estimate. The Yellow Submarine files in question, at least, do have correct meta-data. I just checked.
The Agent and Scanner for the library are both set to “Plex Music”.
I forgot one thing: is ‘Prefer local metadata’ activated? Only activate it, if you 100% trust in your embedded metadata. If you don’t, you better leave it off.
With that out of the way, to upwards in the hierarchy to the artist ‘The Beatles’.
And trigger ‘Refresh Metadata’ on this artist.
This may take quite a while.
Wait at least 10 minutes before doing anything else.
I did a Refresh Metadata on The Beatles. No luck. I waited for quite a while and then reloaded the web page just to make sure all data is fresh from the server. No change that I can see. The Yellow Submarine is still wrong.
Try populating the ‘Album Artist’ meta tag
as well as populating the ‘Track #’ tag.
You can use mp3tag’s “Convert filename -> tag” feature with this format string to do that automatically (since your file names contain the track number already): %track%-%dummy%
[edit: I used the wrong separator in the format string. Your track numbers are separated by a dash, not an underscore. Sorry about that!]
Did you add the path M:\cool_rock to your library or just M:?
So actually, it’s not M: that’s in my library. That’s a network drive to my linux box so that I can access the files from Windows. Plex is running on the linux box, and the files are located in /storage/music/cool_rock/.... The cool_rock directory is added to the library, as are several other directories under /storage/music.
I populated Album Artist and Track #, as you suggested, and then performed a Refresh Metadata on the album. This fixed the problem for this album. So I guess I will embark on the exciting task of seeking out “broken” tracks and repairing them.
