BTS are not nominated for the Grammys.You are right, this is not a surprise for us who had scales fall from our eyes. Even so I was shocked to the core to see that they have a total of six Grammy nominations and in the same time I can not help to remember their first red carpet at the Billboards. As if it was yesterday. They were a bit shy, so well-mannered and humble, to use an 'epithet' so-much loved by the Army. But my appreciation (there was never more than that) is a big zero now when they are at the peak of their success. Fabricated as it is.
The video you posted is about bighit sumbmitting BTS so they can be nominated
You have to propose the artist to the grammys so they can be selected. Bighit suggested BTS for those nominations but the Grammy did not accept yet
The nominations will be announced December 5th
And it looks like they will have a new colaboration soon (the other artist has a D in their name)
