M.I Abaga and his record label, Chocolate City, are suing Queenbridge legend Nas.

According to the report, M.I and Chocolate City have filed a lawsuit in New York State Supreme Court claiming Nas didn't deliver the verse they wanted.
-
In the lawsuit, Nas and Mass Appeal Records' Ronnie Goodman, are accused of duping Chocolate City after they had paid the rapper $50,000 (about N18million) for the verse.


According to the lawsuit, in 2013, Nas and Goodman entered an agreement to contribute a verse to a track from M.I.

The details of the deal were that Nas was supposed to mention "M.I, Chocolate City, Nigeria, Queens, New York—NAS's hometown—, Mandela, Trayvon Martin, and the struggles of Africans and African Americans" in his verse.
Nas went on to deliver a verse but it didn't mention any of the subject matter Chocolate City had asked for.

The Nigerian label requested that the Queens rapper to re-record the verse, and three year later, it hasn’t happened despite them delivering the $50,000 payment.
