I think you have picked three good examples of artists that will be revered for centuries to come for different reasons. The Beatles defined an era and yet their music has a timeless quality that is somehow globally appealing. Michael Jackson and Elvis both had this global appeal as well. Michael will be known for the great music as well as his showmanship and bizarre persona. -It's worth mentioning that Beethoven and Mozart were both odd in their time too. Elvis is the one of the three that I personally don't enjoy listening to much at all. However, I can understand that there are many people that differ with me. I just don't think his music translates well over the generations. But definitely, I think people will revere all 3 a century from now. I would add Bob Dylan to the list as well. EDIT: Since we have you hear, perhaps you could clarify the meaning of some song lyrics... :)
