It's odd how you can sometimes identify sounds... take, for example, the movie THX 1138, George Lucas' first feature film. The movie kind of sucks, you can tell that it has lots of "oooh, wouldn't it be CRAZY if something happened right here! Maybe a naked girl for no reason!"
Anyway, at one point in the movie, there's a guard beating a prisoner on the TV and you instantly say, "That's the start of Mr. Self Destruct!" I haven't listed to that song in 10 years, but pop, that's what it is. Very interesting.
THX 1138 is available for streaming on Netflix.
