Your analog doesn't make sense.. She's a great choreographer, but it's dated.. I said I hope that she will WORK WITH, not have them to do it.... there is a difference
There are many sounds nowadays that are engineered with the latest technologies which makes it difficult for the singers to sing it live because it comes out completely different from the original. And since this is the debut of the song, I guess you have to be as close as possible. After everyone has familarised themselves with it, then it is much easier to sing live, i guess. not defending. just my opinion. I wish she could be brave enough to sing live again after all that she suffered.
