Tags not recognized by Windows Media Player

Hello everyone !

I just have changed the tags of all my 900+ songs playlist. Everything's fine except for 86 of these songs.
They are all MP3 files. Tags are changed properly in MP3TAG and can be seen in the software.

Problem : these 86 files can't be read by Windows Media Player (VLC can though) or on all Android music reader apps. I notice that the tags do not appear in the properties of these files.

Did anyone have this problem before and if yes, how can it be solved ?
Thanks in advance ! :slight_smile:

Do these files have V2.4 tags?
WMP does not understand these.

These files have apparently ID3V2.3 tags...

The I would check the files for integrity - see this thread for linked utilities:
