I have a mental 48 hour music loop in my head. When I listen to a song I haven't heard in a while (perhaps on the radio while I'm asleep and the radio is trying to awaken me!) .... well, about 48 hours later, I'll find that I'm humming that song. I'll then wonder where on earth THAT song came from, since it has, of course, been years since I've (consciously) heard it.
So all of these tunes will probably be back in two days. Curse you, Red Baron!
This was a fun thread!
