Okay, so as to not be completely greedy and hog this whole thread, we'll play a game.
If you're, say, watching a youtube video, and hear a song that you recognise or like but you can't, for the life of you, figure it out, then link it here and someone might know.
Okay, here's my link (http://www.youtube.com/watch?v=IH2vhCCz9v0&mode=related&search=). It's the song from 00:08 - 00:25. It's not much, but maybe someone will recognise it.
Lux Aeterna. By the Kronos Quartet, from the movie Requiem for a Dream.
