The late J Dilla is honoured on different occasions throughout the album. Track 1 is credited to be "Supervised by J Dilla". Track 13 "Can't Stop This" is devoted to his persona, the first part being an edited version of a track ("Time: The Donut of the Heart") of his "Donuts" album, released three days before his death. This version comprises vocals by Black Thought. Secondly, a string of kindred artists reminisce about J Dilla in the form of answering machine messages.
