I view american idol as the ultimate karaoke show with the coolest prize. I learned long ago never to judge anyone until they open their mouths to actually sing....I have heard some fantastic singers and I also have learned, sometimes to my horror, that a lot of these people who are painfully awful REALLY AND TRULY BELIEVE they are great singers.
The difference between a karaoke operator and Simon Cowell is that we're not allowed to tell people they suck. I've been cheerleading some of the same horrible singers for 29 years who are still singing the same song, and slaughtering it that they did the first time I met them.
