i'm not really a beatles fan, but i do think they deserve credit for all their influencing. they were rebels at the time too when you think about it.
i think that some songs they did were ok, but i wouldn't classify myself as a Beatles fan.
you should read one of the GuitarWorlds were they have a great article about Sergeant Pepper and all the recording techniques and ideas. i really enjoyed even though i'm not a Beatles fan.
well, i just think that they were a big influence and that music would be different without them.
