Here's why:
* Initial Screening: There are many stages of the American Idol audition process. The first stage often involves a preliminary screening where producers listen to a large number of hopefuls. Not everyone passes this stage.
* Limited Time: The judges have a limited amount of time and can't see everyone who shows up.
* Producers' Selection: The producers often choose the best singers or those with unique or interesting stories to move on to the judge's rounds.
* Show's Structure: The show focuses on the most entertaining auditions and those with the most potential. It's not practical to showcase everyone.
So, while many people audition, only a select few get to sing for the judges on American Idol.
