LOS ANGELES (AP) — A jury on Monday found that Katy Perry’s 2013 hit "Dark Horse" improperly
copied a 2009 Christian rap song in a unanimous decision that represented a rare takedown of a pop
superstar and her elite producer by a relatively unknown artist.
The verdict by a nine-member federal jury in a Los Angeles courtroom came five years after Marcus Gray
and two co-authors, first sued in 2014 alleging "Dark Horse" stole from "Joyful
Noise," a song Gray released under the stage name Flame.
The case now goes to a penalty phase, where the jury will decide how much Perry and other defendants owe
for copyright infringement.
Questions from the jury during their two full days of deliberations had suggested that they might find
only some of the defendants liable for copyright infringement. The case focused on the notes and beats
of the song, not its lyrics or recording, and the questions suggested that Perry might be off the hook.

But in a decision that left many in the courtroom surprised, jurors found all six songwriters and all
four corporations that released and distributed the songs were liable, including Perry and Sarah Hudson,
who wrote only the song’s words, and Juicy J, who only wrote the rap he provided for the song. Perry was
not present when the verdict was read.
Other defendants found liable were Capitol Records as well as Perry’s producers: Dr. Luke, Max Martin and
Cirkut, who came up with the song’s beat.
Gray’s attorneys argued that the beat and instrumental line featured through nearly half of "Dark
Horse" are substantially similar to those of "Joyful Noise." Gray wrote the song with his
co-plaintiffs Emanuel Lambert and Chike Ojukwu.
"Dark Horse," a hybrid of pop, trap and hip-hop sounds that was the third single of Perry’s
2013 album "Prism," spent four weeks atop the Billboard Hot 100 in early 2014, and earned a
Grammy nomination for Perry, who performed the song during her 2015 Super Bowl halftime show.
Her attorneys argued that the song sections in question represent the kind of simple musical elements
that if found to be subject to copyright would hurt music and all songwriters.
"They’re trying to own basic building blocks of music, the alphabet of music that should be
available to everyone," Perry’s lawyer Christine Lepera said during closing arguments Thursday.
The defendants’ musical expert testified that the musical patterns in dispute were as simple as
"Mary Had a Little Lamb."
But the jury of six women and three men disagreed, finding that the bumping beat and riff at the center
of "Joyful Noise" were original enough to be copyrighted.
Perry and the song’s co-authors testified during the seven-day trial that none of them had heard the song
or heard of Gray before the lawsuit, nor did they listen to Christian music.
Gray’s attorneys had only to demonstrate, however, that "Joyful Noise" had wide dissemination
and could have been heard by Perry and her co-authors. They provided as evidence that it had millions of
plays on YouTube and Spotify, and that the album it’s included on was nominated for a Grammy.
"They’re trying to shove Mr. Gray into some gospel music alleyway that no one ever visits,"
said plaintiffs’ attorney Michael A. Kahn during closing arguments, when he also pointed out that Perry
had begun her career as a Christian artist.
Jurors agreed, finding that the song was distributed widely enough that the "Dark Horse"
writers may well have heard it.
Kahn and Gray declined comment but smiled as they left the courtroom after the verdict.
Lepera and other defense attorneys also declined comment outside court. Perry’s publicist did not
immediately return an email message seeking comment Monday evening.
Perry, a 34-year-old pop superstar and "American Idol" judge, brought laughs to the proceedings
when she testified during its second day when her lawyers were having technical troubles getting
"Dark Horse" to play in the courtroom.
"I could perform it live," Perry said.
No performance was necessary after the audio issues were fixed. Jurors heard both songs played
back-to-back in their entirety at the end of closing arguments last week.
