Kanye West has reportedly waged a legal battle against EMI Publishing, UMG Recordings, Bravado International Group, and the JAY-Z-founded Roc-a-Fella Records.

According to The Hollywood Reporter, 'Ye filed lawsuits against the companies Friday in Los Angeles Superior Court. The legal documents are said to be heavily redacted, but it appears the dispute is over unpaid royalties and publishing rights. UMG, Bravado, and Roc-a-Fella are listed as co-defendants in one suit. EMI, which began handing the rights to Kanye's songs in 2003, is listed in a separate complaint. The latter suit states Kanye had inked a deal with the publishing company shortly before he released his debut album, College Dropout. According to TMZ, the rapper claims that by the end of 2011, he had written more than 200 records that were given to EMI. Though specific tracks aren't mentioned, the outlet reports the records "include some of the most influential and successful songs in his catalog."

"There now exists a dispute between Plaintiffs and Defendant EMI regarding the parties' rights and obligations to one another under the EMI Contract and Extensions," the EMI lawsuit reads, as reported by THR.

Kanye is being represented by high-powered firm Quinn Emanuel litigator Robert Schwartz. He is seeking a transfer of property and declaratory relief. He is also alleging unjust enrichment on the plaintiffs' part.

Back in October, Kanye revealed he had tried to purchase his publishing rights from Sony/ATV, the parent company of EMI. The rapper made the claims in a 10-minute video posted on social media.

"I went to go buy my publishing from Sony/ATV, and they said it was $8 million, $9 million," he said. "And went I went to buy it, they told me no, I couldn't buy my publishing [...] I have the money to buy my publishing, and they told me that I couldn’t buy my publishing. It's like the control, like, I can't say what I want to say on SNL."

'Ye went on to address Jon Platt, who is set to replace Sony/ATV's longtime CEO Marty Bandier later this year. 

"[...] I got the money. So, big Jon, Marty, whoever is involved, I need my publishing. I got the money," Kanye continued. "I'm not gonna say the S-word (referring to 'slave'). I'm not Prince; I don't need to write it on my face."
