Katy Perry song Dark House has sold 5 million copies worldwide. But today is under fire by a Christian rap group who say the singer and her people including produce Dr. Luke stole they song Joyful Noise and turned into Dark House which is full of ILLUMANTI imagery as well as witchcraft message. The tunes sound similar but grammy gospel Act Flame released they tune in 2007 and Katy Perry in 2013. What do you guys think we want to know did she steal or are they trying to start trouble ??
