Jermaine Dupri is suing Sony Music Entertainment over accusations that the music giant owes him and his label more than $18 million in unpaid royalties tied to albums from Mariah Carey, Usher and others.

In a lawsuit filed on Tuesday (July 7) and obtained by Billboard, the legendary hip-hop producer and his So-So Def Recordings accused Sony of a “systemic pattern” of using “contemptuous accounting practices” to underpay royalties for many years.
