TBT - Rainbow's "A"

Released: March 5, 2011

I'm honestly still bitter that this was, and still is, the main highlight of Rainbow's career. When "A" was released it was actually, as I've understood, quite popular in South Korea, and rightfully so. It's one of my favorite songs of theirs and favorite K-pop songs in general, and I remember being mesmerized by it when I first watched the video. Imagine what position they would have been in right now had DSP not been terrible at managing them. It's painful, really.
