Thank God that you are not a judge. Obviously you don't know the difference between an opera aria and Josh Groban's song "You're still you" ---this is definitely NOT OPERA! ( *refer to number 20.) Also I think you should have your ears checked for pitch accuracy before commenting on number 8 being out-of-tune; considering that the stunning number of performers who are out-of-tune, it's a wonder that you picked 8.
p.s. who do you think you are to judge others when you don't know what you are talking about? Next time, say only when you have something to say.
