Well, forgive me for being an ignorant, but I think music should be less about the sounds and ideas in it, and more about the actual MUSIC. The best example I can think of is baroque music, although it can be highly complex, it is pretty basic stuff compared to other styles. There is no in-depth timbral or philosophical exploitation, and the rules are simple and intuitive. You can even improvise multiple voice baroque music in real time! STILL, - for me - it is one of the best sounding music genres there is, probably the best sounding one! Nothing works for me like listening to the St. Matthew Passion. And now the important part: I can play baroque music with rock or jazz instruments, and it still sounds great! Why? Because the actual MUSIC is great. I can also play baroque music for a homeless guy or a construction worker and he will love it! The challenge in making modern music is to make something that is new and original, but sounds just as good as old music. Renaissance music was great, Baroque was great, Classical was great, Romantic was great, Late Romantic, Impressionist, Expressionist, all great. We should write music that is beyond philosophy and sound, instead of writing music that sucks but has a very intellectual academic reason to suck.
