The Beatles were the most "popular" band of all time and they wrote/played mostly "pop music", but did have some good rock and roll tunes. In addition, they were extremely talented and gifted musicians (especially John Lennon in terms of rock and roll songs, while McCartney was a "pop" master, so to speak).
Yet, in my opinion, and the opinion of many rock musicians, Led Zeppelin was the most influential rock and roll band ever, and there album sales and attendance figures are "through the roof". During the 1970's, when the Beatles were dealing with the "Yoko" issues and Lennon's desire to go solo, etc, Led Zeppelin, along with the Rolling Stones, the Who, and probably Elvis, were the biggest music acts around.
Just ask almost any rock and roll band/musician today as well as pop musicians and almost all of them still listen to Led Zeppelin to this day. They were rock music masters. Bonham, Page, Plant, and John Paul Jones were SO TALENTED, each pretty much among the best at what they did at the time. Listen to all to their their albums (I think they had about 10 of them). Every one is so different and their variety/innovative songs is amazing. Almost no two songs they wrote and played are alike.
