[15] The song "Love", which appears as the bonus track, contains a sample of "Sunblocks" as performed by American electronic rock duo Ratatat and was originally recorded in 2013 during the Satellite Flight: The Journey to Mother Moon sessions, however had been officially unreleased due to sample clearance issues.

[16][17][18] Neil Yeung of Allmusic gave it a 4 and half out of 5, writing “packaged together, this compilation provides a fascinating peek into both Cudi's evolution and artistic scope, presenting a figure that maybe doesn't get enough credit for the creative leaps he's taken and the inspiration that he's provided to contemporaries and up-and-coming artists alike.”[19] Notes ‡ Sales+streaming figures based on certification alone.
