I thought the sample sounded OKAY, not great. The article certainly made it seem like this has a lot of potential though. The biggest thing missing was the ambient white noise and transitions between notes- two things that are more commonly found in music played from a physical instrument. I think that is their biggest remaining challenge. If you have purely synthesized music then you might be able to make the difference between the original and the compressed imperceptible. Voice synthesis technology exists as well that, if perfected, would make it possible to generate music and lyrics entirely from the command line. Then again in the 1980's some people predicted we would have flying cars and colonies on the moon by now so it could just be hype.
