The metadata “WWW _xxxxx_…” (and even “WWW_xxxx…_)” above look like field names, but they are not.

“WIKIPADIA”, “SHAZAM ALBUM” and other _descriptions_ from the image above are parts of user data.

This is a Mp3tag UI design decision, specific to ID3v2 WXXX frame 🤷‍♂️:

> You can try `WWW DESCRIPTION` as field name via the extended tag dialog. It then uses the `DESCRIPTION` part as description for the `WXXX` frame
