What movie trope is this?

[David.Seth2]

You know how some movies or shows will have serious scenes, maybe of death and destruction, and its accompanied by music that just doesn't seem to fit? What is that trope called? Here are some examples I can think of off the top of my head to give you an idea of what I'm talking about (keep in mind that all these are potential spoilers but since most of them are anime I'm sure most wont care):

Dr Strangelove (Vera Lynn - We'll Meet Again)

Metropolis (Ray Charles - I Can't Stop Loving You)

Cowboy Bebop (Yoko Kanno & Gabriela Robin - Green Bird)

End of Evangelion (Shiro Sagisu & Arianne - Komm, süsser Tod ... its mildly NSFW)

Mars Attacks (Slim Whitman - Indian Love Call .....this one the music actually causes the destruction lol)

I know Ive seen more, but I can't think of any at the moment. Anyway, what would this be called? I realize that it might not actually have a name or proper trope, but Im asking anyway. I was trying to explain to a friend about these types of scenes, and he hadn't seen any of the listed material so I was at a loss to describe the effect. Also, if anyone else knows of scenes similar, list or post them.

Oh man, thats awesome. Thanks a lot. I tried going through their lists, but it was just too much.
Cant believe I forgot the use of A Wonderful world in Bowling for Columbine

and I just saw Antichrist not to long ago... it opened with a "soundtrack dissonance"
despite what the video says its actually the opening scene (NSFW... you see man ass. But hey, its Willem Dafoe)

One of the best tropes out there - a great usage on Flashforward the other day:

I love this trope. I think in the best of circumstances it works better than no music at all.

Wow, Flashforward really loves this trope (spoilers for those that haven't seen it):
