I really shouldn’t try to listen singing when I’m working.  A human voice will pull me out of the work.  Particularly when it is counter tenor, David Daniels singing  Che Faró Senza, Euridice.  It is sublime.  If I were the least bit religious I would call it the voice of god, but I don’t want to take away from the genius of Gluck who created this music.  It’s probably why music is such a strong thread through the EDGE books.  It’s mathematics made tangible.  The music of the spheres.
