Here are some North Korea Music.
“We Will Follow You Only” (Chosŏn’gŭl: 우리는 당신밖에 모른다) is a North Korean hymn dedicated to the country’s leader Kim Jong-un. The song was first released on the Korean Central Television, right after Jang Sung-taek was arrested on December 9, 2013. People in factories and schools were required to sing the song, sometimes on camera. (wikipedia)

The way they greet Kim in the opening of the performance is very funny.
To be honest, the North Korean music sounds like church music very much , If you replace the word ‘Kim’ with the word ‘father’.
