Oh, I know that. The casting agents will always suggest songs from the show if people come in not having a prepared audition song. What I'm saying is that if you ask most people, hell if you watch American Idol, the advice will be to do something different in order to be remembered as the person who did something different and also not be compared to the other gazillion people who sang that same song. Not to mention, if you have a prepared audition song you know that song frontwards and backwards from practicing it so long as well as being used to singing it with different accompanists. The kids they showed were singing flat, sharp, fast, etc.
