JAYZ in Trouble as NPG Records is suing Roc Nation for overstepping an agreement Prince signed with them before his death.

Prince's record label is through playing around with Jay Z .it just sued the rapper's company for illegally streaming just about every hit song the late singer ever released.

Prince's NPG Records is suing Roc Nation for overstepping an agreement Prince signed with them before his death. According to the docs, Prince made a deal for Roc Nation to stream through Tidal the last album he released before his death  "Hit N Run: Phase 1."

But NPG says Roc Nation decided it also had the greenlight to stream almost all of Prince's catalog, and started doing that on June 7, 2016 which would have been his 58th birthday.

NPG says none of that streaming was authorized and it's now suing Roc for copyright infringement, and also to block any continued streaming of his music ... outside of that final album.

They don't mention a specific dollar amount, but the damages would be enormous. According to the docs Tidal jacked "I Wanna Be Your Lover," "1999," "Little Red Corvette," "Cream," "Purple Rain," "Controversy," "Pop Life,"  just to skim the surface.Seriously, the list goes on for more than 3 full pages.
