So I'm preparing a writeup on that (rightfully) dead genre of Korean pop, and I've got the reason they exist, a few songs saved, a few facts about it and all. But Namuwiki isn't giving me enough answers to my questions and I'm scared to venture into korean forums because I don't wanna get caught up in all the right wing/dictatorship-supporting stuff. So I figured I'd ask on here. (I'm gonna call the genre PS as in Propaganda Songs lol. NOthing healthy and/or patriotic about them)

1) So the most famous PS song is Jung Soo-ra's "아, 대한민국/Ah, Korea", from what I've gathered. It was written and recorded out of free will. Apart from that, many singers were basically forced to record a PS song and put it on their album. Did people actually enjoy PS songs?

2) How could Lee Sun-hee have covered/released "아름다운 강산/Beautiful Rivers And Mountains" in the 80s when Shin Joong-hyun was one of the biggest banned artists under Park Chung-hee in the 70s? Did Chun Doo-hwan suddenly change his mind regarding the banned artists? Or did the song get "propaganda-washed" or did Sun-hee get some special permit or something? I'm confused

3) How widespread were PS songs in everyday life? Were they sung/taught at school/college or something like that? Was there a seperate radio station or so? Or did they just exist for the sake of it?

4) Why did some artists have PS songs on their album, but some didn't? Min Hae-kyung doesn't seem to have a PS song on her albums (I searched through her discography on Melon, Bugs and on discogs) despite promoting through the whole 80s. Yang Soo-kyung and Lee Sang-eun didn't either. While Kim Wan-sun, Lee Ji-yeon and Park Nam-jung have one on their first albums. Does anyone know why? Or did they actually have one and removed it from the tracklists/reprints once the dictatorship fell?

5) Are they still in use today, and if yes, where? For example, are songs like "아, 대한민국/Ah, Korea" or "시장에 가면/When I Go To The Market" or "정화의 노래/Song Of Purification" still sung or listened to during national holidays when it's time to be ~patriotic~, or are the ties/references to the dictatorship so strong that it's out of the public memory?
