According to the The Hollywood Reporter, Kendrick Lamar is now being sued by Woolfsongs Limited for not getting a sample cleared for his 2011 hit record “Keisha’s Song (Her Pain).” Woolfsongs Limited, which manages the works of progressive rock artist Eric Woolfson and his band The Alan Parsons Project, is seeking an injunction and an award of compensatory damages for misuse of their song “Old and Wise.”

The lawsuit says that the parties discussed the matter in April, but never settled before the release of the album.

Section.80 has sold 130,000 copies worldwide since it was released on July 2nd, 2011.
