Well, when you get onto the argument of, as long as it rocks, who cares.
Personally I have a bit of trouble with that. I have a hang up about effort, and artistry and integrity, and I`ve always loved techno for it`s stance against the mainstream.
I mean, what`s wrong with aguilera miming a whole live set for an hour and a half, it rocks the crowd right?
What would people think of radiohead if they just did a live gig to a dat, and just jumped around on stage?
I don`t think people would be impressed.
Sure it`s important to rock the crowd, but personally I feel better knowing that I actually had to work a bit to do it.
I think it has something to do with ego.
