I know this is a VERY old topic, answered before, but I recently ran into the problem anyway.
Windows Explorer is not capable of reading ID3v2.4 tags. However it can read v 2.3 tags.
If you update your tags and they don't show up in Windows Explorer columns or details, do this:
- Start MP3Tag.
- From the menu bar, go into Tools > Options.
- Open the "Tags" caret to bring down the tag handling options.
- Open the "Mpeg" panel.
- Make sure that ID3v2 is selected for "Read" and "Write".
- Under "Write", select the radio button for "ID3v2.3 UTF-16" (or "IDv2.3 ISO-8859-1" may also work but I didn't test it.)
[ Redacting previously stated step: 7. UN-check ID3v2 from "Remove". This is UNECCESSARY unless you wish to keep your ID3v2 tags when using the "Remove" function. ]
You can leave other options set if they don't conflict with the above.
Now select your files and rewrite your tags. They should now be visible in Windows Explorer.
