Thanks @ohrenkino for this fairly detailed information. @LyricsLover also wrote me some examples.

Ohrenkino, I'm working on some of my tags with ('Album') ('EP') ('LP') ('Single')

If one day I need to program this type of data with Actions, I'll run some tests. If it doesn't work, I'll write on the Mp3tag Community to see if we can program them.

Thanks for your help, Ohrenkino, and the other volunteers too, and Florian, who gives us great updates with new features that sometimes impress me...
