Surprised no mention made of this "ArtIst" Aiva
It's in the classical domain, but the example at the end of the article seems a rather pleasant auditory treat. It's also apparently officially recognised as a proper composer, somehow.
I also seem to recall reading that the most prodigious composer of music is a chap who has a computer do it for him - he now holds somewhere in the region 100k-200k musical copyrights from the computer generated music, but can't find his name this late in the day and can't attest to their quality..
