PSY (AKA Park Jae Sang) is a Korean pop singer. Here's what Wikipedia says about him:
"PSY received his education in the United States, graduating from both Boston University and Berklee College of Music. He was fined for his first album, the reason being that his music promoted inappropriate content for underage listeners. His second album was also banned."
Clearly that was a ban in Korea and not the U.S. I think he hysterical and his music has a great beat. Plus, from a videographer/editor perspective, the videos are super well produced.
Make sure and watch clear to the end to see the awesome parking garage dance off! (FYI--this video isn't suitable to the younger crowds.)
