This sounds like a good reason not to go wandering in a desert in Namibia. For an installation artist has decided to set up an “eternal” loop of the song broadcast to the local sand dunes. The song may or may not be to your taste once or twenty times but for all time?
There is also that little issue of quite how long eternity is and quite how short the lifespan of human made technology but still, the boom box should last long enough for the local sand fleas to get thoroughly bored:
Very, very, bored.
