It is very mind-blowing that the Japanese can actually manage to make songs so dark yet also make it so that it seems very wholesome when the music videos don't get involved (I just got obsessed with this (https://youtu.be/watch?v=ibjWftkJrd4) song because of Taiko no Tatsujin, I have been playing it and somebody send help (it's about hypnosis, and what's dark about it is that some people can be in a hypnotized state for a very, very long time))
