Taeyeon is main/lead vocal of SNSD, SONE and non-SONE had knowledge her singing ability. I personally didn't know there's voice and dance line, so i didn't really think about it, i didn't know how K-Pop works haha~ when i first watch Genie MV, my eyes were stuck on Taeyeon, so when i watched Gee MV, i was trying to find that face, but couldn't find it hahaha~ her hairstyle and make up were so different >w< and i still didn't know who's who lol~
