Kanye West’s ongoing feud with Jay-Z intensified this weekend after sources say he left Tidal over a financial dispute and threatened the company with a $3 million lawsuit.

According to sources that spoke to TMZ, Kanye West, 40, claims to be owed more than $3 million from the music streaming website that just released Jay-Z’s new album, 4:44, this week. The album contains a song titled, “Kill Jay-Z,” in which the former friend and “Watch The Throne” collaborator featured a verse dissing West.

"You dropped outta school, you lost your principles / You gave him 20 million without thinkin' / He gave you 20 minutes on stage, f--k was he thinkin'?" Jay-Z raps on the track, appearing to reference West's 2004 album, The College Dropout.

West’s lawyer reportedly sent a letter to Tidal this week following two weeks of unsuccessful negotiations, alleging the subscription-based streaming service is in breach of contract. West’s reported legal threat to Tidal claims “The Life of Pablo” album brought in 1.5 million new subscribers, for which he was promised  -- but never paid – a bonus.

West’s legal dispute also claims Tidal reneged on a contractual obligation to reimburse him for music videos released through the service. Tidal responded that West simply didn’t deliver the videos required by the contract.

TMZ reports that Tidal’s lawyers responded to West’s legal threats by maintaining they have an exclusive contract with the rapper and will sue him if he should attempt to go to another music streaming service.

This isn't the hip-hop duo's first dispute. On Nov. 19 of last year during a concert in Sacramento, Kanye stopped the show to rant about his relationship with the music mogul. "Jay Z — call me, bruh," he pleaded, adding that "you still ain't called me. Jay Z, I know you got killers. Please don't send them at my head."

Tidal currently operates in 52 countries and has more than 48.5 million tracks among its listings and 175,000 music videos available. The Norwegian company Aspiro AB maintains the service. Its parent company, formerly known as Project Panther Bidco Ltd., was acquired by Shawn “Jay-Z” Carter for $56 million in March 2015.

Jay-Z is currently a major shareholder in the company, along with Sprint, which purchased 33 percent of Tidal in January 2017.
