Tuesday we posted the Kanye West-produced track, 'Brooklyn Go Hard,' with Jay-Z, featuring Santogold, from the upcoming 'Notorious' soundtrack, and now, we've just learned that the album will feature a surprise guest: Notorious B.I.G's 12-year-old son, Christopher "CJ" Wallace.

CJ joins Jay, Jadakiss and Faith Evans on the soundtrack, that film producer Wayne Barrow has confirmed will also feature three previously unreleased Biggie Demos. "We kept everything as is, in its raw form. This is what got him the [recording] deal, plain and simple. His fans have been asking for it for years...It's incredible stuff," Director George Tillman Jr. explained in a recent interview.

As for young CJ's involvement with the project, Big's son will appear on a remix of his big papa's classic 'One More Chance,' which has been described as "emotional," so we can only guess what that means.

Check out the tracklisting below:
1. 'Notorious Thugs' (featuring Bone Thugs-N-Harmony)
2. 'Hypnotize'
3. 'Notorious'
4. 'Juicy'
5. 'Party & Bulls---'
6. 'Warning'
7. 'One More Chance (remix)' (featuring Faith Evans)
8. 'Brooklyn Go Hard' (Jay-Z featuring Santogold)
9. 'Letter to B.I.G.' (Jadakiss featuring Faith Evans)
10. 'Kick in the Door'
11. 'What's Beef'
12. 'World Is Filled'
13. 'One More Chance' (featuring CJ)
14. 'The Notorious Theme' (composed by Danny Elfman)
15. 'Microphone Murderer' (previously unreleased demo)
16. 'Guaranteed Raw' (previously unreleased demo)
17. 'Love No Ho' (previously unreleased demo)
