I agree mfirst, we can argue about the music, it's all down to personal taste in the end. You can never succeed in persuading someone that a song or artist is 'great' if they themselves don't get it. Just like trying to convince someone that a joke is funny if they don't see the humour.
I am of a certain age that I was young teenager when The Beatles burst upon the scene and if you weren't there to experience this then I will never be able to describe the impact they made on my generation. Nothing like them or their music had ever been heard before and this hit the whole world, both politically, musically of course and culturally, like no act had done before or since.
Listening to their music now and seeing them as they were, is all looking back with the knowledge of everything that happened both then and afterwards in 'pop music' terms and they just become part of this history. You've probably heard "She loves You" or later, 'Sgt Pepper' perhaps hundreds of times over the years, but just try to imagine for a moment if you'd never heard pop music like this ever before or seen a group like this before and suddenly you turned on the radio or TV and there they were!
But, just like my 'joke' analogy earlier, if you don't get it then that's all there is to be said.
