Jermaine Dupri files an $18 million lawsuit against Sony Music Entertainment, alleging the company underpaid royalties tied to multiple releases associated with Dupri. According to the complaints reported by outlets including Variety and Billboard, Dupri claims Sony did not account for or pay royalties properly for albums and recordings involving artists such as Mariah Carey and Usher, and also cites other acts including Xscape and Kris Kross. The suit says Sony used accounting and payment practices that were not lawful and that resulted in millions of dollars in unpaid or underpaid royalties owed to Dupri and his label. Dupri filed the complaint on Monday, and the allegations are described as centered on royalty calculations and payment handling over time. Sony has not been described in the reports as having responded publicly to the claims at the time of publication. The case seeks damages reflecting the alleged shortfall in royalty payments.
