No, just no.
U2 and The Beatles are not terrible musicians.
I've said it before, playing an instrument = easy
Wrting good music = hard
U2 are terrible musicians, Bill Bailey proved it.
What you seem to be talking about is a matter of taste and the majority of people liking the songs. That doesnt mean it is great music. Nor does it mean that they are great musicians. Black Sabbath were influential, but that doesnt make Ozzy an amazing vocalist (which he isnt). There are so many extremely talented lesser known musicians out there, and with much better songs, progressions, time changes etc. People have mentioned Trivium. I would say that the members of Trivium are much better musicians than the beatles.
May as well change the name of the topic to "top 5 artists that sold the least amount of records"
and then we had blueberry pie...
