I'm wanting to add a title and contributing artist to an MP3 file, because this is how I format and store music. Here are some pictures and a description of what's happening:
Here's the file. Notice, no EXIF data added so far. Just a file name.

It's not in read-only mode, either.

So I go to details and I can indeed edit them.

Applying them appears to work as well (although causes no changes to the file from the folder view).

But as soon as I hit OK... back to square one. Blank EXIF data from the folder view, and nothing in details when I open properties again.


Does anyone have any ideas what might be causing this and/or how to resolve it so I can save the changes successfully?
Thanks for any assistance.
