explain her :
lol very popular indeed, amongst the top echelons of Kpop.
In fact i was gonna list her as the only other obvious exception to the "Main Vocal not being the most popular member" argument. But then of course, i remembered a name that i literally wrote in my rant.
Believe me, i too have no clue why Yoona is so popular. Her looks are completely average to me, i see 10 women like her every time i go to the mall tbh. And no one says anything about her vocals or dance abilities. But somehow, she captured the hearts of the entire nation and became one of the top It Girls of 2nd gen.
If it was up to me, Tae would easily be the most popular member of SNSD. She has some solid solo songs, including Weekend which is criminally underrated and one of the best retro songs ever in Kpop.
