Jay-Z and Kanye West are the latest artists to feel the legal wrath of R&B singer Syl Johnson. ” Johnson filed a complaint against the rappers in Illinois federal court last Friday alleging that they illegally sampled his music for their album “Watch The Throne.” Johnson specifically claims that Kanye and Jay used a portion of his track “Different Strokes” to create their tune “The Joy.” Johnson also alleges that Kanye originally wanted to sample his music for his solo album “My Beautiful Dark Twisted Fantasy,” but was unable to get clearance. Back in August when “Watch The Throne” was released, Johnson’s label, the Numero Uno Group, posted a message on its blog saying Johnson is a “veteran of copyright infringement cases” and still has plenty of fight left in him.

Johnson, who created many successful songs in the 1960s and 70s, has accused many musicians of illegally using his music over the years. He has filed lawsuits against artists like Michael Jackson, Cypress Hill, and Jefferson Airplane, and has also gotten acts like the Wu Tang Clan and Kid Rock to pay for their use of samples.
