21 member group, Double B 21, just released a new MV for their track, "SOS." We're still not sure how the group is going to work out, but there's been rumors that they will be divided into sub groups. �Either way, this music video does display some group shots of all 21 members, albeit very briefly. With that said, I still can't come to call this an actual "music video." �It just seems too cheap, and home video-like, although it's probably pretty expensive catering to 21 members, so that could explain why. �But hey, at least the song is not too shabby. �Check it out for yourself!
