Katy Perry is being sued by Christian musicians who are claiming that the hit song “Dark Horse” infringes on their copyright of a 2008 song.

Marcus Gray and Chike Ojukwu of St. Louis as well as Lecrae Moore of Atlanta and Emanuel Lambert of Aldan, Pennsylvania filed the lawsuit on Tuesday.

The lawsuit also names several capitol records members and says that Dark Horse was based on the Christian song Joyful Noise.

Joyful Noise has won awards in the Christian and Gospel music world, but the gospel group who sings it now claims that it has been “irreparably tarnished by its association with the witchcraft, paganism, black magic and Illuminati imagery” of Perry’s song Dark Horse.

The song Dark Horse has caused problems for Perry before. Several months ago, a Change.org petition was created to make the singer remove imagery of a man wearing a pendant bearing the word “Allah” while standing in fire from the Dark Horse music video.

Several people in the Muslim community felt that the imagery was a display of blasphemy. The petition was successful, and the pendant was removed from the video.

Perry has not yet released a statement about the lawsuit. Do you think Dark Horse was based on the Christian song Joyful Noise?
