bts best vocal moments / vocalist analysis + debunking bad vocal clips, a thread

first to preface this : i am a trained vocal singer, trained in aria/opera singing (basically the most technical level of singing which requires to most refined technique).

I will assess the as POP SINGERS because if i assessed them according to classical singing standards, literally every idol would have bad technique. Furthermore, I will be assessing them according to their BEST clips singing.

This is because their best clips of them singing is them showing the fullest of their capabilities. Everyone has bad days with singing. There're times when I have a hard time with technique and sound horrible. By looking at their best clips, we're looking at +

what they're capable of when using their voices right, and that's what makes a good singer.
This thread will have 6 parts to it :
1) debunking
2-5) best clips of the member and in depth analysis of each member
6) rankings with my opinion & comparing their vocals together.

the ranking is not meant to say "this member is the worst singer, they need to leave" or that they're a bad singer. If anything I think BTS have really good voices and only have a few flaws. Do not bash any member based on the rankings or anaylsis.

Do not bash me for this thread. I'm giving my unbiased opinion and am not trying to set up any member. Furthermore, if you have anything bad to say about bts vocals, please leave and don't comment it. BTS are hardworking and no singing is perfect or consistently good everytime.
