Music ... Tuesday?

The vidding discord has linked me a similar song finder and poking around the site has been a nice time-waster. The interesting bit for this post is that all the artists and songs are tagged with the Spotify genres for them. Most of them are completely explicable (dance pop, symphonic power metal), but some of them are more ... exotic.

Like Fallen Angel or Slayer (which are the exact same picture) or Pixie or Hel. WTF? Why those names? ("Hel" seems to be essentially just "female metal vocalists' solo careers".) I have no Spotify, so this is my first time encountering these labels. I guess I'll spend a few weeks absent-mindedly clicking on the artist names and seeing if I can discover anything cool. (I already did with Phoenix by Enemy Inside, even if I did discover it by clicking on an "example audio of genre" button that didn't so much as bring up the band's name so I had to google the lyrics to figure out who the fuck was singing...)

So! Do any of your favorite artists/songs have a weird and wacky genre name associated with them? What's the oddest such you found?
