^ Well this is an Ayu board isn't it? I'm not going to be in this thread saying Namie lip synched this one or Arashi lip synched that one etc. (which I have done on other boards)
Anyway, yeah lip synching/backtracking always stands out for me pretty easily. For example when the first bootleg clip of Energize came out I immediately said it was lip synched, but most people said no it isn't, you can't tell anything from the clip etc etc. Yet as the tour went on more and more reports came in about it being lip synched. It just bothers me when I see vocal performances that get praised when they are likely not even fully live.
