Rainbow is another one of those groups (like Miss A) who put out music that I don't care too much about because everyone has already done it and done it better. But unlike Miss A, Rainbow isn't limited by productions by a certain label head and I've been waiting for a good song from the girls since their Kara copy cat single "A". I'm guessing DSP (who are dealing with the restructuring of K-Pop darlings Kara since Nicole and Jiyoung aren't renewing their contracts), they needed something to get the public talking about something non-Kara related, so the Rainbow Blaxx subunit was born.
