Five music labels have filed a lawsuit against streaming music service Pandora Music, saying the company is violating state law by refusing to pay labels and artists for its use of recordings made before 1972. U.S. copyright law doesn’t cover recordings made before 1972, but the five music labels—Capitol Records, Sony Music Entertainment, UMG Recordings, Warner Music Group and ABKCO Music & Records—argue that Pandora’s use is a violation of New York state law.
