It's so popular to hate on Nickleback, but they were popular for a reason. They wrote one hell of a pop rock song, but with Chad's voice, it somehow sounded harder. It just hurt them that all of the songs sounded alike.
My pop radio career was in the hight of their success, so nobody has heard their songs more than me.
They are certainly not a "disgrace to music". I just hope to never hear them again.
