?You have "software engineer" and "musician" in your bio? That means I probably shouldn't try to 'splain to you how (I think) vinyl works. I've learned from previous (gentle!) spankings that this is generally not a good idea.
That's how I find out which of my friends worked on CoreAudio, who owns a modular synth, and who was in a rock band and played with bands like Life House before they suddenly said "C++ is cool, I wanna work on Spanner, tell me about the atomic clocks again."
