Music of the Spheres? Flying Singer?

Music of the Spheres was just a whim, but perhaps it's apt - I make music, and I play with space stuff, and "music of the spheres" is an ancient space reference, referring to the motions of the celestial bodies. Orbital mechanics, just like Orbiter, sort of. Flying Singer was the name of a horse in a race I once accidentally attended. I'm not a gambler, but as a songwriter and a (semi-grounded) private pilot, the name Flying Singer had a certain appeal. I bet on the horse and he made me a few bucks. When I needed a nom de web for some forums and such, I adopted the name for myself. Pretty random, but also not, the way a lot of things are.
