So buying a smart TV and connecting it with streaming box/stick for accessing streaming services does seem to be the best solution.

You can simply load up mp3 files into a spare/old phone (or your present phone/iPad) and use vlc media player. Your phone will be your mp3 player. I do the exact same thing with old phones lying at home.

Super dramatic aren’t they lol!

That sounds like a very interesting fridge to say the least.
