But what's "success"? I think most musicians who play music that might be classed as "rock" these days are happy if they're able to simply make a living playing music. You don't have to sell-out arenas, dominate airwaves, and line your walls with platinum records to be considered "successful", and to equate ubiquity with relevance is a terrible idea.
This is what I meant above by "it's like punk never happened". Yep, I was being somewhat tongue-in-cheek, but since when has rock music been about mainstream success?
