Well no one has mentioned this band yet, and I may get a lot of hate for saying it, but most over rated band in my eyes is The Beatles.
They were iconic, and people went insane for them, but I just don't see their appeal. A lot of their lyrics sounded amateurish apart from a couple of exceptions, and they just sound so repetitively dull to me.
Obviously I am just basing my views on youtube videos because the band was before my time, but I think one of the things that set them apart from the other bands of that era, was they had charisma as individuals. And just like in wrestling, charisma takes you to that upper level, it sets you apart from the rest.
I am kind of torn on my own opinion now....I think they were a good band..but made average music, if that makes sense. Like their genius was in their minds, more than in their sound. I would rather hear them talk, than make music.
