Well, you are undoubtedly right, Kaveman but I am a person who, according to my geek son, "should not be on the Internet". Nevertheless, here I am. He has tried to explain how iTunes works but w/o success. I doubt if an online video or a "good book" is going to do the job. I just don't get it.
Does VLC load mp3 players other than iPod?
You said, "Why on earth would you change your User Account regularly, mine has migrated since 10.1, over 11 years." If I have done this it was because I didn't remember I already had an account. "mine has migrated since 10.1, over 11 years" means nothing to me. Sorry.
Anyway, I appreciate that you are exasperated by ineptitude. Me, too, in my own field which is not technology, obviously.
