2010: The Best of Kanye West

The rapper-producer released a statement late Wednesday declaring that versions of the track, which had turned up on blogs and elsewhere online in the past week, are “bogus and unsanctioned” and that he and his team are taking measures to "identify and prosecute the persons responsible for leaking this material."

West continued the missive by saying that the leak “violates the artist's creative intentions." An a capella version of the song was first performed by West last year inside Facebook’s corporate office south of San Francisco.

Read the statement in its entirety 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.”
