First Katy Perry's "Dark Horse" angered Muslims; now it's drawn the ire of a Christian rapper. Flame and his producers this week filed suit against Perry, claiming she stole his 2008 song, "Joyful Noise," Celebuzz reports—and, as if that's not bad enough, the lawsuit claims "the devoutly religious message" of the song "has been irreparably tarnished by its association with the witchcraft, paganism, black magic, and Illuminati imagery evoked by the same music in 'Dark Horse.'" Compare for yourself here and here, or check out why Muslims were also unhappy with the religious imagery in Perry's song. (More lawsuit stories.)
