The Beatles were a 3 year band. Came into the US in 1963 and petered out by 1966. Their music is shallow at best, liberal at worst, and had the musical quality of a bunch of toddlers.
Beatles were the white mans transition away from the soul sound that dominated the 50’s and early 60’s
They replaced the 4 tops, Smokey Robinson, etc by offering an initial soft sound that transitioned to elements of hard rock, and lead to the electric era.
Who was writing better popular music in the 1960s?
