(I guess that is how popularity goes. Most people know madonna but definately not the best singer out there. There are probably thousands of singer that havent been discovered and only sing in the shower or to their family) Promotion goes a long way over substance.
obviously tastes differ, but yea some reactions are over the top. Like they take it personal (same thing happens on the subject of singers, instead of simply saying they are not good or "meh" at best, they get demonised like it is the worst thing that ever happened to the world)
