Favourite Piece of Incidental Music in a TV Show

[Misty-Moo]

What's your favourite piece of incidental music from a TV show?


For me it's this -

"I am The Doctor" by Murray Gold from Doctor Who
(or, in my head, the "something thrilling is happening" piece of music)

So, what's yours?
Bearing in mind that by incidental music,
I mean a piece of music that is used regularly in a TV show, but isn't the theme
​

The sad music that plays, usually when a character dies. Makes me want to cry.

This is used in Supernatural a lot. (I think there is only one season so far where this song wasn't played at all.) I don't really watch Supernatural that much anymore, but I still really like the song.
