I rarely listen to them however their music was brilliant. You sit with a bunch of Rush or Metallica fans and they''ll talk about all the time changes those bands do, which are obvious and in your face while the Beatles were subtle. Many tunes move from 4/4 to 3/4. But its used as a musical tool not as a "see how cool we are" vehicle. Their melodies are amazing, use of strings and other instruments and most importantly their studio work. Prior to the Beatles, the recording studio was the last place musicians went, once songs were complete. The Beatles wrote in the studio, pioneering all kinds of recording techniques. They basicially invented psychadelic music.
This is my fav tune, released in 1966 and still sounds as modern as todays music.
