The late, great Prince, who died on April 21 of this year, was always fiercely protective of his music. And now his label is carrying the torch after his death. TMZ reports that Prince’s record label, NPG Records, has filed suit against Jay Z’s Roc Nation for allegedly “overstepping an agreement Prince signed with them before his death.” Prince’s label claims the late artist had struck a deal for Jay Z and Roc Nation’s Tidal service to stream Prince’s last album he released before his death, Hit N Run: Phase One, but then Tidal began streaming most of Prince’s full catalog without authorization. It’s now reportedly suing Roc Nation for copyright infringement as well as attempting to block the steaming of Prince’s music—save that one album.
