I know there have been rumors as certain blogs have posted that track list with those iTunes bonus tracks but nothing official. Hopefully this info right here confirms it. My apologies if this has already been posted, although I don't think I've seen it yet.

While that record sits on ice, the boom-bap master revealed that he did lend his trademarks scratches to a record "Mama's Boyfriend," an iTunes bonus from My Beautiful Dark Twisted Fantasy.
"[Kanye] actually hit me the day before he had to turn the album in to do some scratches on a song called 'Mama's [Boyfriend],'" Premier says of a record West debuted a capella this summer at the Facebook headquarters. "We just did it like five or six days ago... They sent me a private hard drive. I had to know certain passwords and go through all these steps to get the song. Kanye even sent me an email saying 'destroy all the roughs I sent you.'"
