Katy Perry was found guilty of plagiarism for her 2013 Dark Horse song . A judge ruled that the song is too similar to gospel song Joyful Noise by Christian rapper Flame, TMZreports .

How much money Perry will have to pay is not yet known. The case between Katy and Flame has been running since July 2014 and has finally come to an end after 5 years, to the relief of the rapper.

He believes that Perry has “stolen his song straight away, which has ruined his good Christian reputation”.

Flame posted his song Joyful Noise on YouTube in 2008 and has since received millions of views. According to him, Perry has taken over the underlying beat of the song, something the singer has consistently denied.
