You've said that in at least two stories. Yes you write "I don't know a lot about music--I'm not musical". Well, those are two entirely different concepts...anyway. You claim ignorance and yet call everyone else ignorant in saying they're overrated?
I truly believe you don't get music because of what you said about the Beatles. I couldn't give a rat's ass if the Beatles changed music. When you connect to music emotionally it doesn't matter what anyone else thinks. In my youth the Beatles became part of my way of feeling. Same for Cat Stevens which no one else I knew thought much of.
I can't stand the early Beatles. Throw out everything before "Hard Day's Night" and it won't bother me. Michael Jackson was a genius. Why would he do a duet with Paul McCartney? Why would Steve Wonder, another drop-dead musical genius? What do they hear that you don't?
Listen to the Beatles Albums from "Help" on. Educate yourself ;)
I hated Steve Miller in college. All my friends played him all the time. Then in my late 40s I put on one of his songs and then it clicked. I played him constantly for a year!
Tastes change. Or sometimes you don't get someone in one part of your life, but do in another. It's one of the great features of music!!!
To blather on a bit more. There was a music writer for the New Yorker. Like you, she was always making quips that Joni Mitchell was overrated. Then one day I see the headline "I Get Joni Now" or something like that. She was in a cab and the driver was playing it. She asked him to turn it off but then backed down. During the ride it clicked for her.
Joni Mitchell. Another drop-dead genius. "Free man in Paris" That song has it all for me.
