Pete Rock is preparing to file a lawsuit against Nas for allegedly failing to pay him royalties for their work together on the rapper’s groundbreaking 1994 debut album Illmatic, Page Six reports.

According to the outlet, the veteran hip hop producer claims he’s owed royalties from his and Nas’ Gold-certified Illmatic cut, “The World Is Yours,” which he estimates would now total millions of dollars.

Rock produced the heavily sampled hit and is also credited as a co-writer on the song and provided vocals. According to the producer, he and Nas signed a contract that allowed him to take a cut of “The World Is Yours” proceeds. However, Rock says that despite numerous attempts, Nas never honored their deal.

Now, Rock’s attorneys say they’re planning to file a lawsuit against the King’s Disease II rapper later this month.

“Nas and his people have stonewalled me since 1994,” Rock told Page Six on Tuesday (Jan. 11). “My New Year’s resolution is to be compensated for my hard work on Illmatic.”

Since being released in 1994, “The World Is Yours” has been sampled on nearly 100 songs, most notably by the likes of Eminem, JAY-Z, Lil Wayne, Rick Ross and the late Mac Miller. The track was also featured in the Denzel Washington– fronted film Antwone Fisher.

After working with Nas on the hit, Rock — who has also produced classics for A Tribe Called Quest, Gang Starr and more — went on to produce two more songs for the New York rapper: “The Art Of It” and “Queensbridge Politics.” Both tracks ended up landing on Nas’ 2019 compilation project, The Lost Tapes 2.

Besides Rock, Illmatic also boasted contributions from veteran producers like DJ Premier, Q-Tip and Large Professor. Most recently, Nas teamed up with Hit-Boy to release their nine-track offering Magic, which also features A$AP Rocky and Premier; on Christmas Eve (Dec. 25)
