North Korean Music Store.

An online store called KFA eCommerce Solutions (complete with militaristic logo!) is selling North Korean music (folk, military band, and other patriotic and propaganda variety), postcards, and DPRK cartoon!

Even the reviews of the CDs are classic North Korea:

this is exactly what a search for a long time ! for sure the north korea army chorus are the best in this kind of music !! this is a good cd ! the sound is very good ! the voices are extremely strong !! the music is realy good !!
