Katy Perry & co must pay

A US jury has decided Katy Perry, her collaborators and her record label must pay more than $US2.78 million ($NZ4.2m) because the pop star’s 2013 hit Dark Horse copied a Christian rap song. It was an underdog victory for rapper Marcus Gray, an artist once known as Flame whose 5-year-old lawsuit survived constant court challenges and a trial against top-flight attorneys for Perry and the five other music-industry heavyweights who wrote her song. But the amount was less than the nearly $US20m sought by attorneys for Gray and his two co-writers on the 2009 song Joyful Noise.
