Um, UncleBeer? Sir? I would never presume to contradict a Mod, but, well, I only said I’ve HEARD of it, not that I believe it. With all due respect. Sir.

I’ve read that this is usually due to the fact that you did hear it some where first.
Say you are driving, a car pulls up next to you at a light (radio on) but your distracted by your kids (whatever) then you pull into 7/11 - Wow! same song is playing that’s now in your head.
Or you walk past a house that has the radio on…I think you get the idea.
I think the stranger thing is, that if it is a real phenom, it should happen a lot! Not rarely.
