This may be the most beautiful thing I have ever done in my
   life. NOTICE how your brain tries very hard to finish the song,
   then as you continue, if you survive that long, begins to accept
   the long note as acceptable without need for beginning or end,
   while retaining an underlying current of awkwardness. It is
   possible to merge the worlds while they retain their individual
   identities. https://www.youtube.com/watch?v=byBVb0OIx0s
