It's pretty interesting if you go back 50 years from the 1960's and 70's you wind up in the middle of World War I, just before that you have things like Igor Stravinsky causing riots in 1913 Paris because of how extreme his music was. I think major reason earlier music was not as popular was due to how people consumed music. For a long time the only way a lot of people would get to experience music would be to attend concerts, which was a relatively privileged thing to be able to do. Records were one of those things that didn't really take off until post world war I.
