ey sweety next time wear proper dressing, you dont wear ballet to shuffle or moonwalk. the bouncing is screwing the "subject matter" the pace of the music is also almost nearly in the "resonance" region. btw, this shuffle we usually have wedding events that allow dancing at the front. when shuffle music is ON, our 5-10 yrs old kids appear from every corners and nowhere into the middle until the dance floor is full, dancing frantically and very unsychronized can you imagine that? western influence and the net duh. synchronized/group shuffle is fun to watch though, but most of the time they simply look like madness.
