Oh god, how they suck. They make jet-engines look mild in comparison, in terms of sucking power. Their music is a mix of mediocre thrashing, rawk-poses, and Chad Kroeger's odd, growly excuse for "singing."
Two seconds' worth of their music are two seconds too many. I seriously cannot stand more than one millisecond of their shitty, shitty, shitty, shitty, shitty music. I would rather extract my eardrums with a butter knife that I have hammered, using a pair of large, flat stones, into a long, somewhat pointy jabbing implement which could reach down through my ear canal as to better reach said thin membranes, than be subjected to any one of their "hits."
And yet, they sell records. Lots of them. Top of the charts in many countries.
. . .
But, I will say this: Chad Kroeger is an exceedingly ugly man. I, on the other hand, am mildly presentable (given the proper, poor lighting conditions). So we're even.
