[http://help.mp3tag.de/](https://docs.mp3tag.de) says "Names and mapping of ID3v2/WMA/MP4 tag fields" but goes to [https://docs.mp3tag.de/mapping](https://docs.mp3tag.de/mapping) where the table "ID3v2 / WMA tag fields" has no explicit mention of MP fields. Could be clearer!

You mean changing "iTunes" to "iTunes/MP4"?

Surely the MP4 tags are not specific to iTunes.
