Unfortunately music is one of those things that people take so personally that most people are afraid to voice their honest opinions. Just try saying BB King or Eric Clapton suck & you'll be fighting off flame mail for days, even if you honestly feel that way. There's a lot of musicians that I can't stand and honestly wonder how the hell they ever made it in the business or attained 'legendary' status, but I just keep my mouth shut cause there's no point in saying it.
It's like trying to argue the existence of God or the bible or whatever.
Nobody can win the argument cause each person in their own mind thinks that they're own opinion is the correct one.
