How you move me!
I do believe this song is on the soundtrack to the end of the world. My favorite part is 1:48 – 2:39
Then of course there is Caarano Pi.
The first minute of this song nearly brings me to tears when I hear it. After that it kinda goes down hill but is still great.
You should listen to Requiem for a Tower, it is a retake on Requiem for a Dream and is absolutely Majestic and just sweeps me away with its power. I have that as the root for one of my Pandora stations and I love it, brings up a lot of really good Classical music.
interesting song for the end of the world. i would imagine there to be more drum & bass in it. ;)
