These have existed for a while, and I have to say I absolutely LOVE MR removed videos. It's funny after all of the lip syncing accusations, to hear them, uh, lip syncing. Some of them anyway.
And I'm so done with the argument some people have that it's "impossible" to dance and sing at the same time.
This video:
SJ are dancing as intense as BTS do, and they are singing live. It is super, super obvious that they are singing live. Barely any back track. So yes, it's very possible. Do they all sound perfect? No. Do they sound terrible? No. Kangin is off key and flat, Sungmin's voice is a little shaky in parts but not bad at all.
So getting back to BTS... the BWL performance on SNL is hilarious to me, because they all sound like crap more or less until the rapline comes in and they all sound fantastic. Rapping requires the same amount of breath control as singing, so rapline doesn't have it any easier. Jin sounds relatively okay at times, but clearly isn't trained to sing and dance at the same time. Tae sounds okay as well, but he also lacks some vocal control which has kind of always been his problem (flat vocals). Jungkook sounds awful in the beginning but he did get better toward the end. Jimin is just... yikes. I wonder if he's losing his voice or if he does no longer cares and lets the back track sing for him.
