A week ahead of its scheduled release date, Kendrick Lamar's To Pimp a Butterfly is up for sale on iTunes. It's also streaming here via Spotify. You can check out the full tracklist below.

Initially, only the "clean" version of the album was available for sale. Shortly thereafter, the "explicit" version was uploaded to iTunes, as well as Spotify. Around noon on Monday, both versions were taken off iTunes, prompting Top Dog Entertainment CEO Anthony Tiffith to say he was "working on getting the iTunes link fixed smh." (Though the album remained available on streaming services like Spotify and Rdio.) Then, it was put back on iTunes.

In a new interview with the New York Times, Lamar revealed that Flying Lotus made the beat on opener "Wesley's Theory" and that he sampled Sufjan Stevens on "Hood Politics". (The source track appears to be "All For Myself" from 2010's The Age of Adz.) He also visited Compton and Nelson Mandela's cell on Robben Island for "soul-searching" inspiration. Additionally, Lalah Hathaway and Ronald Isley both contributed vocals to the album.
