They are extremely relevant, culturally and historically. They broke new grounds for music, and a lot of today's music would simply not exist without the Beatles, or some of their contemporaries. That alone means they're not overrated.
However that doesn't mean everyone has to love them. It's possible to recognise their relevance without worshipping them.
I think this is a case of the Seinfeld effect where people take them for granted due to them being so influential that part of their sound has become imbued into every single pop band that came after them.
Yeah, there are any number of "But so-and-so did it so much better than the Beatles!" instances, but the thing is that so-and-so wouldn't have even tried if the Beatles hadn't done it first.
Take or leave their music, there's no denying the massive influence they had.
the word overrated means nothing and is used by cowards to try to discourage enthusiasm for things they can never comprehend.. it needs to be burnt on a word pyre.. it's impossible to overrate The Beatles, only a figment of the Matrix would think that..
you're afraid someone will use the word overrated on your enthusiasm.. also, you continue to demonstrate my point by trying to attack me personally.. it's what a coward does..
