We didn’t…we got from music like this.
There wasn’t a decline in art in any form, objectively. Popular music has always been simple, fun – and many times very stupid. Artists like Bach are mirrored today in some profound popular music artists, as well as composers working in the symphonic genre as well.
Someone like Bach would say, regarding the style of modern music linked, “Hey, that’s like this song I heard in the tavern this one time. We were soooo drunk that night.”
