Ad one, a Faraday cage. A metal biscuit box should do it. Those are hard to come by nowadays, everything is made from plastic. But luckily I have one in the garage. It must be at least 30 years old. That will do. Alternatively, use a microwave oven as a safe.

Ad two, entertainment. You have your music sorted, but what if my idea of entertainment involves watching, ehhh, a certain type of movies? That might be tricky without electricity. The ideal solution would be to transfer them onto celluloid and then use a hand-crank projector with a candle for the light source, but who can do the transfer for me these days? I have only found the services that do the transfers the other way around.
