You've heard "Dark Horse": Katy Perry's overwhelmingly bland 2013 pop hit about being a horse. Now check out the original Christian rap song she stole its beat from.

Katy Perry's "Dark Horse" is pretty inoffensive as far as lazy pop music goes. While it's hard to imagine anyone purposely listening to the song in 2019, it's not awful enough to make someone veer their car off the road the second it came on the radio. "Dark Horse" is entirely unremarkable. At least it would be, if not for the fact that Katy Perry stole its beat from a truly remarkable song.
