Katy Perry was named in a suit for allegedly unlawfully lifting her "Dark Horse" hit from "Joyful Noise," a song found on the Grammy-nominated album Our World Redeemed, released in 2008. Flame (a.k.a. Marcus Tyrone Gray), the track's lead vocalist, alongside Lecrae and John Reilly, claim that Perry's 2013 song featuring Juicy Jnot only borrowed from the beat, but then desecrated it with "witchcraft, paganism, black magic, and Illuminati imagery." The plaintiffs are seeking all the monies gained from the "unauthorized use," which could be considerable considering it was atop the Billboard charts for weeks and its video has over 435 million views on YouTube.
