Lmao, I still don't know how to judge idols' singing ability

I mean, I can tell the difference between a really really good vocalist. Especially when singing live. However, at the end of the day, all that matter is vocal color - what sounds good to our ears. When people first listen to the audio our ears are all attracted to certain sounds. 

 

e.g. Blood Sweat and Tears is still one of the most iconic intros vocally in Kpop.
