Kendrick Lamar’s new release, Untitled Unmastered, is available now on Apple Music, iTunes, Spotify, and Tidal.

Whether the blunder was Spotify’s mistake or an accidental leak on behalf of Lamar’s management is unclear, but this isn’t the first issue Lamar has had with a release.

Top Dawg Entertainment, the independent hip-hop label Lamar is signed to, blamed the error on Interscope Records, with Top Dawg CEO Anthony Tiffith tweeting, “I would personally like to thank Interscope for fucking up our release.”

To Pimp A Butterfly earned Lamar five Grammy awards last month, and his legendary performance of “The Blacker The Berry” and “Alright” that night only further cemented the album as one of the most important works in modern hip-hop.

“I got a chamber of material from the album that I was in love w sample clearances or something as simple as a deadline kept it off the album,” Lamar said.

Update: March 4th, 1:20AM: Added Kendrick Lamar’s description of the record as “a project.”
