[INCOMPLETE] North Korea's "Wangjaesan Dancers" from dprktvradio | 1-22

Here are the iconic twenty two clips of the Wangjaesan Art Troup dancers uploaded by dprktvradio between 2008 and 2009. I've been trying to figure out the songs accompanying the dancers, but I couldn't even find half of them! Some of the title cards are really hard to read with my limited Korean skills. If anyone can help, please consider trying to read one of the names of the songs at the timestamps named Unknown. So far only 8/22 are found. However some might be exclusively dance music that isn't found elsewhere which I especially suspect from the ones that have 무용 in an overlaying title screen, they are the majority of unknowns. Anyways, thanks!

*Update*: Thank you to @user-qk7tv1rt8b and @sakaktincharinphataa3752 who were able to find dances 1, 2, 3, 6, 7, 10, 13, 16, 17, 19, 20, and 22. We have now found the names of 21/22 dances. Only WD 12 is left to find!
