Whether you think they`re overrated or not is irrelevant, what is relevant is that they are one of the most influential groups of all time and used the Pixies as their starting point, along with a whole host of other infuences.
As for calling Kurt Cobain an untalented songwriter.........well you just haven`t got a clue have you.
Douchy scene kiRAB, angsty teens etc run after all types of groups, regardless of the group`s talent.
As said above, the reference to Korn and Slipknot is redundant and has far more to do with Mr.Bungle and metal in general.
