I used to love the Beatles as a kid. Fantastic songs and great lyrics.
Then I got to the 80s and then the 90s and although I do like a lot of stuff from the 50s and 60s and 70s - it just seemed that everyone loves the Beatles and I genuinelly went off them (Despite having pretty much everything they've done)
I think it was more a kickback against the 'Establishment' - I don't like a lot of other 'popular bands' for the same reason
Now I've got a bit older, liking or disliking anything because other people like or dislike it is a bit stupid.
Nowdays I can listen to the Beatles (And many other bands I wouldn't have touched with a bargepole) and appreciate the music, fun, wittiness and sadness contained in their songs.
Maybe it's like this for everyone - as I get older, I find I'm coming full circle back to things that actually make me happy rather than worrying about anything outside that.
