If I had a chance to sit down at the DMZ with some Northerners, I'd skip the depressing stuff and ask about them about their taste in music or food, what they like to do in their free time with family and friends, where they got their awesome haircut, etc. Leave the geopolitics to the kings and generals, and connect as equals, fellow citizens of Earth.
If you want a more intense, rockin' song from them that you can actually headbang too, I suggest checking out "Tasume". The live perfomance had pyro and the audience went nuts dancing along. And the outfits, camera work, etc. are much more updated and in HD.
