Someone call Rob Hubbard! Sounds like a Commodore 64 tune. But seriously, it's really cool, and I hope it sells well.
It's hard to know whether it really sounds like that or not. The media was fairly heavily compressed to the point where the human voices were obviously heavily distorted, let alone the output of the instrument itself. An actual-factual violin would hardly have fared better.
If anyone knows where to get much higher fidelity recordings I'd be interested, though I'd expect it "just" sounds like a high-end synthesizer.
