Harold Pinter built a whole play around that idea. I think it is called "Old Times". If I recall it correctly, a man's wife and her old friend from college spend an evening reminiscing about songs from their youth. The man feels totally excluded and alienated, as he has no connection to the songs at all.

"I think there is a way in which light, even trivial songs, can sometimes sneak in under our barriers of cynicism in a way that objectively better songs cannot do."

That's a great sentence. It describes exactly why I was so surprised to find the title song of this thread so moving in the context, in which I heard it. At any other time, I might have reacted similarly to Leeneia.
