Some people just don't realize this is a singing competition.  The worst performances have been delivered by Sanjaya Malakar and so far he has been in the Top 4 and safe.  Granted, Sanjaya is one of the two best musicians in the competition (BeatBoxer is the other), but unlike BeatBoxer (aka, Blake Lewis), his singing has been dreadfully uninspired.  To my surprise, Antonella Barba is letting nerves get the best of her.  She is one of the best singers in the competition, but her performances have been restrained and for the most part, off-key.  Still, she may win this competition.  The best singers have less than a 50% chance of winning (in the past 5 seasons, only 2 winners were really the best).  Remember, LaToya London, Daughtry, Clay, and of course, Jennifer Hudson.  Mem'ries...
