You begin to suspect a ploy when a girl goes out and says she’s the best vocalist on the show and that she’s going to do one of the hardest songs in the world. At first, the judges assumed it was a joke and that she was amusing the crowd with sarcasm. But as always, she was serious. Girls and stage performances benefit from having confidence. She won over the judges and then the whole YouTube audience by boldly claiming that she is the best singer and that this song will highlight her abilities.
