South Korea is hitting North Korea where it hurts, by blasting K-pop girl bands over the border to annoy its neighboring nemesis.

Following North Korea’s fifth nuclear test on Friday, South Korea is planning to send a message to its northern counterparts through the medium of sound and video, the Korea Times reported.

The army is expected to use a large block of speakers complete with a video display directed over the border to blast the people of North Korea with loud pop music and accompanying music videos. It also plans to broadcast both South Korean and international news, via speakers which can be heard from 20 miles (32km) away.

Remember when South Korea blasted k-pop at the North over the dmz speakers bc that was iconic — rain (@scyythee) August 18, 2016

This isn’t the first time South Korea has resorted to sound and visuals to attack the North. In January, the South Korean army resumed a previously suspended campaign of broadcasting music and pro-democracy messages towards its neighbor after North Korea carried out its fourth nuclear test.

The US has said it is considering its own sanctions on the isolated state. However, North Korea has apparently been undeterred from continuing its nuclear development program despite receiving numerous sanctions in response to its previous nuclear missile tests.
