The Beatles defined POP music. They dabbled a tiny bit into rock, but were mainly a pop band.
The Beatles were great pop songwriters, but mediocre musicians compared to many of their peers.

When British music fans were asked to name the members of the best all-star band, the members of Zeppelin were individually selected among all the musicians of the classic rock era....
