Kendrick Lamar is in the midst of negotiating a new publishing deal that could net him well over $20 million, according to BillboardThe move comes as his current deal with Warner/Chappell Music, which he signed years ago, expires.

Lamar's management at Top Dawg Entertainment has reportedly considered a bid for $28 million, as well as another which would offer $23 million ($11 million of which would be acquired upon signing). As Billboard wrote, "Such offers would likely be for Lamar’s entire catalog, but the terms Lamar's camp is seeking weren’t clear."

Lamar's critically acclaimed album Damn (which earned a Grammy nomination for "Album of the Year") helped the 30-year-old rapper hit album sales of 1.13 million units last year, in addition to 2.63 million track sales. Overall, he moved 4.14 million album consumption units last year, bringing his career tally to roughly 9.5 million.
