This week we revisit the copyright case between Katy Perry's "Dark Horse" and Flame's "Joyful noise". This year, the U.S. Court of Appeals for the Ninth Circuit decided that Katy Perry’s song did not infringe because the musical components at issue were not protectable under copyright law. They held that the common musical notes in “Joyful Noise” lacked the originality required for copyright protection. Tune in to hear more details on the decision and this trend of siginficant music decisions.
