I've listened to both songs and I can hear the similar beat playing behind both songs. I'm not sure if I'm convinced the song writers copied the song but the jury was.

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.
