WC, your way of thinking is stupid and that of a snob.
Music is music, it has clasifications but there's no such thing as nonmusical music. That's ridiculous.
Level of virtuosity has nothing to do with it either.
Fall Out Boys play music, as much shit as you may think they are.
Why we think they are shit? Probably because we don't buy what they sell, because we consider it second rate ice cream, and I strongly dislike second rate ice cream, I only like high quality. And what is high quality? It is what appeals to us, whether because we appreciate the effort, the creativity, the catchy hooks, whatsoever.
