The question is, will any of such music be considered 'beautiful'. The underlying philosophical consequences are what are (to me) most interesting in research such as this - they are another piece to add to the argument for aesthetic objectivism.
Music history has great examples of now considered beautiful music that was once (figuratively) spat on. The audience created a ruckus during the first performance of Stravinsky's Le Sacre du Printemps, Wagner looks like, in modern terminology, a "sleeper hit". Past masters who were once ignored are being re-celebrated in Indian classical music. You can tell I have my doubts that aesthetics is objective :)
Oh there are no doubt such examples; I don't consider them as an argument against aesthetic objectivism though, just as examples that our epistemology, to put it mildly, needs work :) It's an argument I've had many times and that has been fought over for 1000's of years and in countless papers and journal articles - to the point where I've given up hope of convincing anyone who knows what the argument is about, because those who do usually have thought about it so much that it's unlikely I will bring up an argument they haven't heard already, and vice versa :)
