This video for "Have, Don't Have" by Dalshabet is another one of my favorites. The song is catchy (that chorus!) and the video is charming. For me it's quirky in a sort of Wes Anderson-ish way and stands out from the ultra-polished K-pop videos other bands usually release.
When we were in Korea a few years ago we spent a day at a wholesale market like the one the video's filmed at which makes watching it especially fun for me.
