The piece that got me started on this mix isn't an actual song. It's NASA's Voyager spacecraft recording the sound of interstellar space. You can find the recording here... http://www.youtube.com/watch?v=LIAZWb9_si4
After starting with the sound of interstellar space, the mix settles in for a 2 hour journey floating on waves of ambient/space music.
