So is it bad because you say so? I mean, I get not liking a band that is mainstream, or even just not liking them because you don't dig their music. We all have personal preferences. What I hate is people who think their specific music tastes are so much more cultured and refined, and they know best what is good and what isn't; and then they get on the bully pulpit to tell everyone who likes that band why they suck. To take your term, those people are a "pant load."
I might hate Lady Gaga and think her music sucks, but if someone enjoys it and gets something out of it, who am I to tell them they suck for liking that music? If they like it, they like it. It takes all kinds.
