Kendrick Lamar faces a lawsuit by Woolfsongs Limited over the 2011 track "Keisha's Song (Her Pain)," featuring Ashtrobot off his critically acclaimed, independent debut LP "Section.80."

Produced by Tae Beast of Digi+Phonics, the Compton emcee recorded the explicit tragedy of a young prostitute for his little sister, telling her to never become one. "My little sister 11, I looked her right in the face / The day that I wrote this song, set her down and pressed play," he raps in the Bridge.

The 27-year-old rapper allegedly sampled British progressive rock band The Alan Parsons Project's 1982 single "Old and Wise" off their sixth studio album "Eye in the Sky" without their consent. The platinum group, consisting of Eric Woolfsen and Alan Parsons, was active between 1975 and 1990.

According to The Hollywood Reporter, the case was filed in California federal court by Woolfsongs Limited, which manages the works of Eric Woolfsen and the Alan Parsons Project, seeking an injunction and an award of compensatory damages. Also, the lawsuit says that the parties previously discussed the matter for a resolution back in April. However, they were unable to settle an agreement because of Lamar's unresponsiveness.

Meanwhile, K. Dot is currently working on the follow-up to his platinum selling sophomore album "good kid, m.A.A.d city." While sitting down with San Francisco-based radio station KMEL last month, he talked about his highly anticipated upcoming record. "It's in the process. We cooking," he said. "I couldn't say. I couldn't give a false pretense on where I'm at. ... I can't even give a date or a time, but it's going to be an event."

The "Money Trees" rapper also said he did not feel any pressure prior to the release of his debut album: "Not really pressure. I think it's like fun if anything because it's a challenge not only for myself, my fans and just me creatively. I think it's more of an anxious type felling 'cause this word 'pressure' was thrown around right before my album -- every interview I was doing -- and seriously I didn't feel it. I was like, 'I'mma go out here and give it my best shot for what I know.' And I'mma do that the second time around."
