Example is that on this little concert all the fans cheered on Yuri and she danced and sang so well!! That shows everyone appreciates her and she is really talented in both singing and dancing.

^ I think she won in dancing but how is she a great singer?

I pick Tiffany! ^^

Hey listen I would like everyone to provide proof or I will just leave the final result to my own devices. It is no good to pick without explaining why. I need videos or songs as proof. This is not a popularity contest, I need evidence or else there is no reason why so- and so should win a pick.
If I am going to write a comment while announcing the winner and the ranking I need reasons please. I don't care who you THINK should win, tiagih wants an article that can explain why to the ranking system and I can't go with "I pick..." or "...^^" I don't know much about SNSD except that they are a Kpop group. Help a brotha out here.

i pick seohyun of course. her voice is soothing and she can harmonized well. nowadays she getting better. she can deliver the song with more emotion. she can control her voice that other members cant. she is a stable singer especially during live performance. she can sing and dance at the same time without her voice being affected. she is the best singer after Taeyeon (and may be jessica)

Seohyun. She's really stable and consistent. Fany has a pretty voice but she doesn't have the same control Seohyun does.

I'm going with Seohyun. She has good control of her voice. She is able to keep her voice consistent while singing low and high. I think this song best shows that link

I also appreciate how well she harmonizes. Example- link (this video cuts out very abruptly, just to warn you)
