That Yoona song is autotuned like HELL, dudes. Yeah, She keeps dropping on my popularity list. I don't like her personality or her singing... I guess she's got a good looking face, but it's like too perfect. Not interesting at all. I'd think she's at the bottom of the list for me now. Hyoyeon continues to climb, tho.
I wasn't too impressed with Yuri's singing in that one, either. But I'll let it slide with her.
Taeyeon and Jessica are generally considered to be the most talented singers, right? I think jessica is really good and has a unique voice, but I also think the natural tone of her voice could be divisive for fans.
