On this lazy Sunday here's some more Korean pop music I'm familiar with only because they play on the televisions (alternating with sports) that provide atmosphere in my favorite Korean restaurant in San Diego. As ever it is the choreography, costumes and set changes that drives these videos almost as much as the catchy tunes.
Rainbow - Sweet Dream (2011): I have no idea what they are saying but it has a good beat and you can dance to it. As one video commenter puts it, "Twinkle, twinkle little star. How I wonder what you are" fits the bridge just right.
SISTAR19 - Ma Boy (2010): This K-pop entry is really hot and sexy and not part of the reserved Korean image I remember from the 1980s. Wow to this. I doubt the positioning of that monkey arm was a coincidence. Marketing!
