When you sing the digits of pi a cappella, you gotta really feel it.
Michael Blake's What Pi Sounds Like: youtu.be/wK7tq7L0N8E
Can't find Noam Elkie's pi piece online, but there's a piece of it here: youtu.be/vmRloJxLlvI
Here's someone who plays pi with piano accompaniment with 0 being before 1, instead of after 9, and in minor: youtu.be/OMq9he-5HUU
Of course people have encoded pi into music in other ways, or just sing the digits without any encoding at all: youtu.be/BDMBtQjS1bQ and youtu.be/-iqVyjOv8X0
Or rap the digits, like in this "Lose Yourself" parody: youtu.be/CS1WlUzjtXU
And there's plenty of other stuff. I believe in your ability to find it.
But however awesome pi music might be, remember: Pi is Wrong!
