If you remember correctly, Kanye West performed this during his media rounds before G.O.O.D Fridays and My Beautiful Dark Twisted Fantasy. We thought this was going to be a bonus on the album, but it hasn’t seen the light of day until now. For all the children who grew up with single mothers, this should resonate deep.
This song isn’t official which is why the stream is off and Kanye’s statement about it is below:
The version of the Kanye West recording “Mama’s Boy” that arrived on blog sites earlier this week is entirely bogus and unsanctioned, and violates the artist’s creative intentions. As is often the unfortunate case, an unknown party or parties got a hold of Kanye West’s vocal track and added their own soundbed to it, effectively and falsely releasing it as a Kanye West track from the My Beautiful Dark Twisted Fantasy sessions. The result in no way resembles the final song Kanye West intended his fans to hear, and he is deeply disappointed that one of the most personal, meaningful and special songs he has ever written would reach people in this way. Needless to say, measures are being taken to identify and prosecute the persons responsible for leaking this material.
Rest in peace Donda West.
