I don't get the interest in The Beatles. I find their music bland and boring.
Everyone says they revolutionised music and the rock scene, but I just don't see it. If it wasn't them, it'd have been another band. Plus, I don't at all count them as a rock 'n' roll band. There was a tribute band to The Beatles on at Sonisphere (UK) and I didn't realise that a band could be SO out of place.
Everyone's entitled to their opinions, but I suspect some people jump on the bandwagon because they think they SHOULD like the music. I'm not saying your teacher and friends are wrong for liking The Beatles, but their reactions seem extremely unnecessary and OTT. No one should get ANGRY at someone else because of their musical tastes; it's all subjective. I love Lacuna Coil, but if you hate them, I wouldn't be angry at you, I'd just accept it as a difference of opinion. Who cares?
And all of this, coming from an English person! Well I never!
