If they put in the work establishing themselves, composing and playing music, recording, touring, and attracting a fan base, then they deserve every bit of it.

I can't stand Kiss, and about 90% of all the other bullshit out there, but its not my place in the cosmos to harsh someone else's buzz about the music they like. My tastes are extremely eclectic, and only a tiny percentage would be into the same stuff I'm into. I wouldn't tolerate criticism of my musical tastes, and I'm not about to criticize someone else's.

Like what you want, WTF should I care?
