Well, this is ridiculous. According to TMZ, Katy Perry is getting sued by a Christian rap group called Flame. They say Katy's "Dark Horse" sounds a LOT like their song, "Joyful Noise," and because of the similarities, their song is associated with witchcraft.

You can listen for yourself here. I honestly don't hear ANY similarities, but I could be wrong. Listen for yourself & tweet me your thoughts @marontheradio
