As far as we are allowed to analyse the processes inside DarwinTunes it looks to me a proof that it is required to have human input to create music.
Only with the rules of music the loops sound boring and annoying. Add human input that rates the quality and do something with it brings basic music after 3000 iteration.
Mozart didn't need these iterations: the reactions of the crowd to a piece of music guided him to improve much faster. The basic music he produced was already superior over the final result of this program.
The same is still happening: music still evolves and the real composers still enter new tracks that haven't been used before. That is where the complexity of our brain is still beating the computer: we can rate our own result.
Just start listening what happens at the edges of the musical/artistical domain, leave the center domain, which contains the music produced by computers that are programmes according the rules of success, and find the real human potential of being creative.
But the program proves that feedback is a required instrument for success, which is where so much companies/developers fail on. They forget to use the feedback and go on in their own truth, not understanding how it is possible that some companies can take the market with ideas from others that failed on them beforehand.
