Now, I think she's a fine singer, but more so than ever, this can just be uncomfortable to listen to when she really goes for it. My opinion is also not helped by the fact that the song covered is one that I have never been able to enjoy, no matter who sings it. It's still better than Whistle though.
This is bad! I do not like her at all now. It starts of okay, but as she approaches the high notes, her screaming and grunting just ruins it, and shame that everyone likes her. She is overrated!
