I'm so surprised that Tae Yang is nobody's favourite member!
He is the best : beautiful voice, handsome...
But still I personally prefer Dae Sung, he has the best voice of the group ^^
(I kinda think Seung Ri is useless but...)
My favourite songs are Haru Haru (that's how I discovered the group), Heaven, Always (english version :p), Wedding dress (ok that's just Tae Yang ^^") and Somebody to love (can't stop listening to it, really addictive!).
I'm thinking of becoming a songmaker, and if I do, you'll have loads of Big Bang songs ^^
