I think that, for the time, the Beatles were extremely innovative and different. Controversy aside, when they started doing drugs is when they got kinda groundbreaking. While they’re not as musically complex as some modern Uber-dense Prog metal band, they still deserve to be recognized as giants in musical and artistic history. I am not really a Beatles fan, as there’s only ten or so songs of theirs that I regularly listen to.

To really answer your question I just don’t know, man. It’s like sometimes I think there’s no such thing as “overrated”. Plenty of underrated bands though.
