It's not that her voice is terrible, it is that the producer of this video was a ****** and auto-tuned everything.
If you listen to her other videos and even an interview where she sang the star spangled banner, her voice sounds great!
And that last comment, if you are referring to her appearance, then I have to disagree.. she is still 14 and her looks will improve as she gets older.
OT(kinda): No, I don't listen to her music, but I do research and listen to more than one song by an artist before I judge. She has a good voice and has potential. I use to be one of the haters who despised her, but when her other music came out, it showed how crappy the producer of her first video was. #Puddingproof
