(What's K-Pop, you ask? Quoting from Wikipedia:
K-pop (an abbreviation of Korean pop; Hangul: 케이팝) is a musical genre originating in South Korea that is characterized by a wide variety of audiovisual elements. Although it comprises all genres of "popular music" within South Korea, the term is more often used in a narrower sense to describe a modern form of South Korean pop music covering a range of styles including dance-pop, pop ballad, electropop, R&B and hip-hop music. The genre emerged with one of the earliest K-pop groups, Seo Taiji and Boys, forming in 1992. Their experimentation with different styles of music "reshaped Korea's music scene". As a result, the integration of foreign musical elements has now become common practice in the K-pop industry.
K-pop entered the Japanese market at the turn of the 21st century and rapidly grew into a subculture among teenagers and young adults of East and Southeast Asia. With the advent of online social networking services, the current global spread of K-pop and Korean entertainment known as the Korean Wave is seen in Latin America, India, North Africa, the Middle East, and elsewhere in the Western world.
So there we go!)
I pretty much chose these at random. Do a YouTube search of "Kpop Christmas", and you turn up a lot of stuff, and that makes sense -- this is an enormous genre, and yet I'd bet that most Americans have no idea about it!
