I used to work with a lot of young people and some of them told me they hated the Beatles.
So I would randomly play Beatles songs and occasionally ask them what they thought.
Turns out they never even listened to the Beatles except for maybe a couple of pop/radio songs.
It was just a fad to hate on them
That is not surprising to me in the slightest. Honestly I just posted this because I knew it would lead to a discussion I'd love to read. People have such strong feelings on music.
As one of the "young" people at least when it comes to the Beatles, I don't hate the Beatles but I absolutely don't get the hype living decades after their big run. A few songs are annoying because of overplaying. That colors the band to a lot of people my age. I find them mostly boring and seeing the hype at the time is wild, but so will the people 20 years from now for my music. When people feel like it's over hyped then they "hate" it. I find most of the Beatles music as inoffensive and a little boring. Don't hate it but don't care for it. I think most haters probably feel similar but being controversial makes the conversation more interesting.
