I see that you have added a fully functional **ITUNESACCOUNT** tag edit. Great to be able to edit the Apple Store ID email address in **Mp3tag v2.64** (nice). I was editing some of my iTunes albums that are in .m4a format with **Mp3tag v2.64**....
I noticed that you don't have an add **iTunes "Purchased By"** action programmed into Mp3tag v2.64. There also is no action coded into Mp3tag v2.64 to edit iTunes "Purchased By" for albums with a pre-existing **iTunes "Purchased By"** tag. So, if I want to edit the "Purchased By" tag in an album purchased on the iTunes Store, I can't edit the tag with your application. So, I had to manually recode this detail in each .m4a file of my albums one audio file at a time. You have to be really patient to do this for even 2 albums.
I am trying to help you add this feature/action to Mp3tag v2.64 or Mp3tag v2.64, but not sure what you are using to code Mp3tag v2.64. Anyway, I had to open each .m4a file with a Hex Editor, and edit the "Purchased By" tag manually. I know what address this information resides at. Just give me credit for this in the next release, and we are cool. They call me, mU$!c inc.
I was reading through the code of an .m4a file  , and it looks like you just need to add several lines of code to add this tag to a file that was ripped from a physical CD or a .m4a file that as not an iTunes purchase. These lines of code are generically coded into the beginning of all audio files that are purchased from the iTunes Store.
[🙂 What do ya say, Florian Heidenreich? Takes too long to edit this tag manually for like 5 albums.](http://imageshack.com/f/iqo65XLYj)
