jebus, no one is telling anyone to change your taste in music, we're telling you, in no uncertain terms, that simple plan arn't a good band, they dont have talent, they make paint-by-numbers music, dont do anything in it that shows anything more than a basic level of ability on their instruments and the singer couldn't carry a note if it had handles on it.
and yes, slipknot do have talent, Jim and Mick are both excellent guitarists, Corey has a great vocal range and joey is arguably one of the best drummers in metal. simple plan have not one member that can rival any of them
