Well

I was at a bar last night and they sang karaoke. One of the men who sang told me I should check out this Joni Mitchell song,
Dry Cleaner from De Moines, live version, as the best song ever recorded. I posed the question to the table to name the one song they'd want with them when they were deserted on an island alone for the rest of their life. This is what he named. Never heard of it, or heard it, although I know Joni Mitchell.

So, if you had only one song to listen to on a deserted island for the rest of your life, what would your song be?
