When I read missives like this, I kind of despair for the younger generation. This poor misinformed Redditor just does not understand the tidal wave of change to the entire music scene that The Beatles caused, using their Fifties musical influences and the rising local scene to reimagine and reinvigorate popular music with a basic musicality that transcended genre. And then, they grew and reimagined the scene once again, using rising studio technology in masterful, innovative ways. Artists from all walks of life began recording their material as well, cementing their work in the public consciousness. You can't really overestimate their influence.
