Did you know that if you translate the numbers of Pi into musical notes and record it and upload it, you'll get a cease and desist letter because SOMEONE HAS ALREADY COPYRIGHTED PI ... set to music, that is.
Take a look at this, anyway, while you still can:
Frankly, I think it would be great if musically-inclined mathematicians did their own interpretations of pi (maybe starting with a different digit in the sequence or going longer or changing whatever musical minutiae necessary) and uploading them.
Oh, and here's Tau, which isn't quite as interesting in my opinion, but your kilometric may vary.
