This song is not for the common ear so sorry if you are unable to appreciate it. You clearly are missing something great though. And that voice at the background during the chorus drop sensationally creeps me out It's saying something like this "the common side effects include nervousness, insomnia, nausea, agitation, anxiety, sweating, visual problems, psychosis, numbness, dizziness, headaches, weight loss" The live performance is even more dope. Hyunjin's part with the human wave at the back! Support SKZ!!! These guys are extremely talented it's scary!
