Several of the tracks on the album can be found with a bit of searching. The great track by Rachid & Fathi, "Habit En-Aïch," can be found here.
Berber singer Idir's song, "A Vava Inouva," is quite well known. Jane Goodman discusses it at length in her essential book, Berber Culture on the World Stage.
Here is Kri Kri's "Wahdi."
"Chenar le blues" from Les Abranis
Smail Chaoui's "N'sani N'sani" (it's the second song on this Youtube vid)
Djamel Allem, "Ourestrou"
The rest? We'll just have to wait til the album comes out.
