K-Pop has a variety of different elements and is a music genre from Korea.
I have never heard of it before. Has it ever been to the States
Yes, there are a few K-Pop songs that I have heard good big in the USA. It is the most popular in South Korea and has Western elements of pop.
Can you recommend one of the songs for me to try? 
I'm not sure of a specific song, but the group BoA has some famous stuff from what I can gather from 2003 and onward.
Oh that is nice to hear. Are the BOA americans
No I think they are also South Korean. Most K-pop groups are, but the irony is that most of their songs are generally composed by Europeans or Americans.
That is amazing. Have we ever heard any singer that is american born before
There are many great American singers, but none that do K-Pop from what I know.
Alright. Which other music originate from north korea?
