I am a musician and I've used generative/aleatoric techniques many times.
Carefully crafting sounds, defining my own generative rules and keeping adjusting each subtle parameter until I've achieved the desired results is the farthest I've been in this territory.
On the other hand, I've always despised experiments like this. And I hope there will always be more in what we perceive as art than just selecting a genre, a scale, some sampled instruments and pressing a button.

Even Mozart played with chance (http://en.wikipedia.org/wiki/Musikalisches_Würfelspiel).
