The Fox's Wedding, a rapid-fire song by a guy who likes to make music about kitsunes eating people's guts. Kitsunes are way creepier yokai than pop culture would have you believe; there's all sorts of possession and shapeshifting going on in spooky fox stories. Why do they do these things? I mean they're yokai! Japanese monsters don't need a reason to be violent and terrifying!
English lyrics available through closed captions, though the song is so out of control that it's even hard for Japanese speakers to really get wtf is going on.
And now, an actual human being singing all this!
