7:50 PM PT -- Jay-Z sold his share in Roc-A-Fella back in 2004 and no longer has any involvement in the company. A source close to Kanye makes it clear, there's absolutely NO beef with Jay in filing the new docs.

Kanye West is suing Roc-A-Fella Records -- the company once owned by Jay-Z -- and EMI, the company that helped him launch his career ... because he says he's owed a lot of loot.

Ye filed 2 lawsuits Friday ... one against Roc-A-Fella, claiming he signed an exclusive recording agreement with the company. The suit is heavily redacted, but he's asking for a declaration of his rights over a dispute he's having and he wants money.

Kanye also filed a lawsuit against EMI April Music, claiming they owe him over a music dispute.

According to the lawsuit, obtained by TMZ, in 2003, the year before he came out with his breakout album, "College Dropout," he signed a contract with EMI. The suit claims by the end of 2011, Kanye had written solely or with other writers more than 200 songs and gave the rights to those songs to EMI.

Those songs include some of the most influential and successful songs in his catalog, although the suit isn't specific.

The suit is heavily redacted, although it says there is a dispute and he wants a judge to declare his rights under the contract -- presumably for money.
