Girl freaks out when she can't sing

Obviously I've been spending too much time on youtube lately.. Been stumbling upon a video called "Kids react to viral videos".. Basically the guys of the show would put bunch of viral videos on youtube to the kids (and soooo adorable at that).. And see what are their thoughts of the videos.. The one that actually caught my eyes was this one..

**Word to the wise , do not go that crazy on putting the volume up when you hear this on headphone.. .. You've been warned **

I was like literally deaf for about 2 minutes after watching this video.. Not because of her singing (though I gotta admit it's pretty terrible.. but.. she could practice and get better) but rather because of her constantly screaming throughout the video when she could not hit the right note!
I mean, girl, if you really wanted to do the tryout, just go ahead and sing to your heart's content.. Who cares about how shitty your voice sounds (except for the one who on the judging , of course , but then again , it's the confidence that also counts).. And stop cursing! You still a kid!
