The Beatles screwed everything up.
I tend to agree. They recorded some good pop/rock music, but had an enormously disproportionate influence, mostly negative, on the American culture.
I was a math nerd, not really into music then. I marveled at the insanity of my sister, and other females, who literally became hysterical over The Beatles.
My sister once made me crawl behind the sofa on hands and knees, to listen to their lyrics from the speakers, so that I could write them down for her.
I thought they were overrated then, and think they are overrated now. No one is that good, setting aside the decadent effect of their image and influence.
They were OK until they went to India ... they returned as kooks and then proceeded to screw everything up ...
My dad concurs with you!
