Weeks after South Korea began blasting K-pop and anti-Pyongyang broadcasts from loudspeakers along the border with the reclusive North, a decades-old propaganda war may have erupted on a new front - South Korean karaoke parlours.
 Socialist sing-songs are unlikely to resonate in the liberal, capitalist South, but Seoul’s National Security Law has since 1948 penalised people for distributing North Korean propaganda and lawmaker Hong Moon-pyo, of the ruling Saenuri Party, said the songs were like poison.
North and South Korea are still technically at war after the 1950-53 Korean War ended in a truce, not a peace treaty.
“Long live, long live, general Kim Jong Il!” goes one of songs available on select karaoke machines in the heart of Seoul, Hong told Reuters.
“Dear leader” Kim is the late father of North Korean leader Kim Jong Un, part of a dynasty that is considered divine in bellicose North Korea, which has threatened to destroy Seoul in a sea of flames.
“These karaoke machines have the power to break down our mentality and ideas. They are like a poison mushroom that can infect 50mn South Koreans,” Hong said. His office said it was not sure how widespread the use of the karaoke propaganda was — it had only found two so far, both in areas of the capital frequented by ethnic Koreans from northeast China and North Korean defectors.
