I am afraid I have done that aeons ago, even got her a PC and screen loaded with 60's music but I am afraid that was a no go as she wants to be with me when she watches the videos.
The only way I can calm her down is with Elvis Presley playing on the top right monitor, I move this monitor to point to her whilst I carry on working, the only time I mute it is when a call comes through from a customer
Wife can not operate iPad's, iPods, PC or any device that was not around 20 or 30 years ago any longer, this includes a microwave, front loading washing machine with fancy dials, mobile phones except the one I got for her with a special app for "Elderly use" (push face picture to call that person) she even struggles with answering a call as she forgets how to swipe the button to answer (this, I wish I could change but Android phone will not let you change this feature with the app I am running)
She has a book of her kids phone numbers and addresses written down and prefers to use this
My wife has never been into technology or any new device invented after the 1970's no matter how I try to explain how to use such devices. I have even put permanent marker arrows drawn on the washing machine controls to turn the knob to the arrow and push the GO button, she simply can not work this out or understand the instructions
So I do it all, my life is better if I work the gadgets but listening to Elvis Presley and only Elvis Presley is hard to take on board as I can put the same 2 hour concert on every night and she watches it as if it was the first time she has ever seen it
I really understand. My mom used to love soap opera, I just memorized all dialogues of 10 years or 'friends' and some movies with jonny deep. ( when mum went CH I wanted to trash all DVD)
Try to introduce other singers ,even not so efficient as Elvis, that can give you some Elvis break. Mine break was a looping of penguins walking on Edinburg zoo (I downloaded from YouTube )
