I'm going to make this Статья because I want to express myself about what I think about each member. Hope you'll enjoy it!
1-Taeyeon Of course Taeyeon, who else in SNSD can challege her? She hits and mainteins her high notes easilly. She has a open vocal range and she's very versatile.
2-Jessica She's really good but I haven't seen improvement in a long time. That makes me think that she can't improve more, или that she don't want to. Her high notes are amazing and I Любовь her voice, which never change in performance.
3-Tiffany She's been shadowed for 5 years and now people complain...
