This is a youtube channel:SMP FLOOR which posts video of dance.  SMP FLOOR is run by SM Entertainment(SME). SME is a one of biggest companies of Korean entertainment. We can see dance video by SME artists.

Their dance is so amazing that I regenerated same videos many times. Moreover, SMP FLOOR posts many versions of same dance. For example, one was taken with a fixed camera. Other one was taken with moving camerawork. Like this, we enjoy a lot of kinds of dance video.

Recently, dance has a big influence on trend. Actually, Tiktok is a very popular application in the world. On youtube, some dance videos were regenerated 100M.
