Has anyone done a project with a genetic algorithm and quantitative input from humans to produce generative music? Seems like it would be not to difficult to source listeners via some kind of songbattle site[0] or Mechanical Turk if you wanted to to AB tests. [0] Maybe different strains of the same algorithm competing head-to-head rather than through AB testing?
