(AllHipHop News) Rap star 50 Cent has been hit with a copyright infringement lawsuit by an aspiring rap artist from Atlanta, Georgia, who claims he owns the original license for the beat to the rapper's biggest hit single, "I Get Money."Tyrone "Caliber" Simmons, 28, claims he purchased an exclusive license for all the rights to use, record, publish, re-produce and perform the "I Get Money" instrumental beat, which was produced by William "Apex" Stanberry. The lawsuit, which was filed in the United States District Court, Eastern District of New York, claims that 50 Cent, Aftermath Entertainment, G-Unit and Shady Records knowingly infringed upon his instrumental track, which was included on 50 Cent's third album The Massacre."The misappropriation of copyright-protected material is an endemic problem in the music business, and particularly in the genre of hip-hop/rap This is one such case," said Louis D. Tambaro, an attorney at Red Bank, N.J.-based Marks & Klein, LLP, one of the firms representing Simmons. "Our client was granted exclusive rights to the 'I Get Money' instrumental and was unceremoniously cut out of the loop when the defendants realized they had a huge hit on their hands.""I Get Money" also spawned a variety of remixes, including a popular "Forbes 1-2-3 Billionaire Remix" featuring Jay-Z, Sean "Diddy" Combs and 50 Cent. "This type of infringement is simply not fair and will not be tolerated," added Kevin B. Legreide, an attorney at Legreide & Ceres, Toms River, N.J., which also represents Simmons.
