Jason Derulo, a pop singer, is in a civil trial over the credits for his 2020 chart-topper "Savage Love," where he denies that a session musician on the song, Matthew Spatola, who played guitar and bass on it, is suing him for writing and production royalties. The lawsuit, filed in 2023 and went to trial on April 22, is challenging the absence of a formal work-for-hire agreement, which stipulates that a musician does not have authorship rights despite contributing to a song. A verdict is expected next week.
