Teen Top

If you were doubting the power of Teen Top's comeback (and we highly doubt you were), they proved that they're back and in a big way, appearing on M!Countdown and performing not just one, but two hits: "Miss Right" and, of course, "Missing You." The group's album "No. 1" came out earlier this week, to much buzz from fans and media alike. Watch their performances below! What do you think of their comeback performances?
