Here is the music video for SISTAR19's song "Ma Boy". It's not really a new video and it released at some point back in May. I mean I was vaguely aware of it's existence, but ignored it for the most part. That is until yesterday, when I met up with some of guys from the Soompi forums. During this meet up we watched a bunch of video on Youtube and one of them was SISTAR19's dance practice video for "Ma Boy".
