Great TV show music (besides theme tunes)

Any great uses of music in TV programmes, either original scores or pre-existing songs (I assume theme tunes have been discussed to death here before)?
As far as I can tell, most TV shows' music is fairly generic, probably as it's cheap and quick, and I'd never really noticed any music in a TV programme until I watched Battlestar Galactica. The music in that programme is absolutely brilliant, and all by a fairly young composer called Bear McCreary. It works perfectly in the context of the programme, but also works brilliantly as standalone music, and I often listen to it on my MP3 player. In fact, I have all four seasons' soundtracks, and they're the only TV soundtracks I've ever bought. Lots of it would be described as classical, I suppose, but there's also some heavy metal and pounding action numbers. It's incredibly varied.

Here's three examples of some of my favourites:

WARNING: On the off chance you listen to some of the music before watching the programme, be careful. Obviously some of the track titles are a bit spoilery (though none of the ones below, but be careful about looking at the titles in the related videos on the side if you're on youtube, especially on the third video!), but some of the music itself for seasons 3 and 4 is spoilery, so don't listen to those before you see the relevant seasons. The music itself for seasons 1 and 2 I'm pretty certain is fine to listen to.









Any other examples of great TV music?
