Either you have it or you don´t

This cover is freaking me out. How is it possible that people sing so beautifully and I seem like a run over cat?
Some say that they are afraid of being heard singing, in the shower, by Pitbull and done a remix, I´m terrified of being heard by anyone and put a muzzle on.
Each one with its own.
I know, you must be shocked, but I never said singing was part of my non-ending virtues list ;) 
For susceptible I´ll say I´m just kidding.
