I suspect there are some good music history buffs, here. I think we can safely say that going back at least 60-70 years that there was a large contingent that thought the "new" music was terrible. Bullitt noted that the "parents said the same thing about the Beatles" and theirs the same about Elvis. Same with the subject of the thread and probably everything in between--punk, electronic, hair bands, grunge, etc.
But how about going back further on folks I think most now can and do consider masters and the greats. Mozart, Chopin, Bach, etc. Or when new instruments were utilized. Did a large contingent view them or music using the new instruments to be "terrible?" Was the piano viewed like the autotuner?
