Hi, When updating the genre tag in Mp3tag I’m finding that the Lumin App does not reflect the updated tag and places the file in the “[unknown]” section of the Genre display when I set it to “Jazz” for example. The change of Genre works OK for most files, but some do not and I experience this issue…

I've just released Mp3tag for Mac v1.9.10 with a fix for the issue where the MP4 gnre atom for GENRE used a type identifier that was incompatible with Apple Music so that "Unknown Genre" was displayed instead of the actual genre. To be fair, Mp3tag used the correct type identifier, but Apple Music …

What kind of file is the stubborn one? MP3? If so, could you check whether you have APE tags in the file? And if so, do you really need them? As soon as the file contains only the data that you want to see, it would be up to the player to register the changes - which means updating the displayed …

My first point of call would be if you can import the file into the Music.App on Mac. If that imports it correctly and the genres show hen the next port of call is that Lumin app

[Screenshot 2025-09-20 at 18.22.26] @mjcm - Apple Music states Unknown Genre as attached. Mp3Tag say’s otherwise. Restarted everything. This has been for a few days of trying.

Can you post a screenshot of Mp3tag -> Command + T (Extended Tags) and in Music -> Command + I (and especially the Details and the File Tab) ?

What happens if you stick the TAG GROUPING -> Jazz to it. Does it reads it then? Let me test something. Will report back Edit: I can confirm this @Florian Genre is not read by the Music App on mac. Grouping also not. But on my test file (M4A) YEAR IS Mp3tag: 1.9.8 macOS: Sequoia 15.7 Edit 2: I…

[image] mjcm: I did a test with Mp3tag 3.31c Windows Running under Wine and also there the tags GENRE and GROUPING are not read ... but the player is still the same? AFAI understood the problem it is the player that still shows the old data while MP3tag does not. MP3tag shows that current d…

@ohrenkino I am doing that. I change the tag, delete the file in Music.App on mac and re-import it I even rename Genres/Groupings etc etc to Jazz1,Jazz2 etc etc to avoid this issue
