I am unable to use ID3editor to modify m4a tags, but I have used a free program called Subler to good effect. However, when I use ID3editor to modify the tags of mp3s, I am able to modify the copyright field, but it does not show up in itunes. Is there a reason for this? Do only m4as truly support the copyright field, or is it just that itunes only supports it for m4as and not mp3s? Any thoughts or suggestions would be greatly appreciated.
