A producer is reportedly suing 50 Cent, Dr. Dre, and Dre’s company, Aftermath Entertainment, for incorporating his song for “P.I.M.P.,” a hit from 50 Cent’s 2003 debut album Get Rich or Die Trying.

Brandon Parrott says he sent 10 tracks to Dr. Dre in 2001 in hopes of getting his music recorded, TMZ reports. Two years later, Parrott said an Aftermath producer told him that the beat from one of his tracks, was used for “P.I.M.P.” by accident. At the time, Parrott accepted the producer’s excuse and signed a settlement deal. However, now Parrott reportedly says he feels 50 Cent and Dre took advantage of him, and is seeking compensation.

Both 50 Cent and Dre have yet to respond to the lawsuit, according to New York, although it is not the first time they have dealt with legal issues over ownership of their songs. In January, 50 Cent won a copyright suit over his 2007 hit “I Get Money,” in which the defendant, Tyrone Simmons —who raps under the name Young Caliber — claimed 50 Cent took the underlying beat of the song from him. Dre won a lawsuit against Death Row Records in 2011, when a judge ruled that the rapper was to receive proceeds from digital sales of his 1992 album The Chronic.
