Yes. It does and it always has.
They reject many good singers so that they can give a place to people who they know will get a good laugh.
I remember something a couple of years ago about there being FOUR auditions before the tv show, and they put all these awful singers through all of them. Just so they could be abused by the panel and laughed at by the nation.
If you've been put through several auditions, what are you going to think? Imagine then, the shock when you get ridiculed?
Vile, vile show. I wish people would object to it by refusing to watch.
