Park Jae-Sang (박재상) is a Korean hip-hop artist that goes by the name PSY (싸이). He is not exactly a mainstream artist, but he has become quite popular for his sense of humor and willingness to make fun of other KPOP artists in his videos. He received his education in the United States and attended both Boston University and Berklee College of Music. This guy probably can speak English quite well.
His latest hit is "Right Now" and I have to compliment this guy on his amazing body. 2PM better log some more hours in the gym because they cannot compare with this guys's abs.
