After much buzz and over a year of anticipation, the ladies of Rania finally make their debut on today's KBS's Music Bank with their debut single, "Dr. Feel Good". The group is comprised of Semi, Riko, Jui, Dee, Joy, T-ae, and Xia; Joy is from Thailand, and Riko is a Korean-Japanese. The girls are reportedly fluent in English, Chinese, Thai, Japanese, and Korean. "Dr. Feel Good" delivers a powerful sound with an addictive melody, a combination that Teddy Riley assures can't be found in other girl groups. Despite his busy schedule, Teddy Riley also took time to direct everything from their music, stage concept, choreography, and outfits. Check out their debut stage below! http://www.youtube.com/watch?v=EydlnPeRYc4
