South Korea has recently retaliated for North Korea's trash-carrying balloon launches with propaganda loudspeaker broadcasts at border areas. The South Korean broadcasts reportedly included K-pop sensation BTS’s mega hits like “Butter” and “Dynamite,” weather forecasts and news on Samsung as well as outside criticism on the North’s missile program.
