^ Whats BS/LL? A boyband or something?
You know, strangely, I watch Johnny's concerts and the lip synching doesn't bother me. haha

I think the difference is a) They don't write their own songs b) The songs are just meant to be fun - no deep personal meaning to the members and c) They don't really hide the fact, its right out in the open like "yeah, we're lip synching - even to the original recording of the song."
So I think its more the deceitfulness of it than the actual lip synching itself that bothers me because she does write her own songs and they do have deep personal meaning to her. And then she goes to the trouble of re-recording flawed vocal versions of the songs to lip sync to in order to hide the fact that she is lip syncing and then they even go so far as to hide lip syncing mistakes by inserting footage from other days of the concert. That's kind of insulting the level of intelligence among fans imo and that is bothersome.
