Oh, I don't know, only because they completely altered the course of music? Every modern band that you listen to has been influenced, however indirectly, by the music of the Beatles. The Beatles were geniuses and innovators. 500 years from now, when people take music history classes and learn about 20th century music, it's the Beatles they will be discussing.

No one says you have to personally like them, but denying their influence is ignorant to an unimaginable degree.
