They were far more than a pop group.
The Beatles changed the way music was recorded and thought about. There's music before The Beatles and after them quite and they changed the way it was recorded, expanded the idea of what it could be, made the studio the principle way to record albums. They turned pop music from throwaway music aimed at kids into a valid artform and are, without question, one of the most important musicians of any genre in the 20th century. They are right up there with Debussy, Stravinsky, Schoenberg, Armstrong, Ellington etc.
Paul Weller and Queen come nowhere close to them. Quite simply, The Beatles changed music.
If you don't believe me, you should
read what their musical peers said about them.
