Kendrick Lamar has been hit with a lawsuit alleging he rapped over a Bill Withers song without permission, TMZ reports. Mattie Music Group, which claims to own the rights to Withers' 1975 song "Don't You Want to Stay," sued over Lamar's "I Do This," originally from 2009's Kendrick Lamar EP. The company is quoted as claiming that Lamar's song "consists of nothing more than new rap and hip hop lyrics set to the existing music of 'Don't You Want to Stay.'" The lawsuit reportedly calls for damages and for Lamar to no longer use the Withers song. Pitchfork has reached out to Mattie Music Group and a Lamar spokesperson for comment.

Update (5:54 p.m.): The copyright infringement suit, filed today in a federal court in Los Angeles, claims Lamar rapped over a "direct and complete copy" of Withers' music, Reuters reports. The complaint says Lamar has "admitted" to using the song, "with a thumb to the nose, catch me if you can attitude." Along with Lamar, Top Dawg Entertainment and a Warner Music publishing arm are also defendants in the case.
