Is a bit of work that came out of Microsoft Research, taking voices and providing a musical backing to it.
There's an advert floating about for it that's sheer awfulness personified.
And there's no way that it's going to produce amazing, emotive music that reaches into the depths of your soul.
But frankly, listening to what it does to Eye of the Tiger, I'm impressed at how well it works. Sure, it's banal and pointless, but the point here isn't that it's produced something you'd buy, but that it's produced something that actually works with the vocal part without clashing at all. That's a very impressive step all by itself.

So, as something you'd pay money for: FAIL. As a harbringer of something that may be very interesting in a few years time? WIN.
(Also, it produces funny things, like that video)
