Question

I just watched the movie it was pretty good and Im actually not a fan of Nick Cannon...but that was messed up how it all ended. Anyway, does anyone know if there is a soundtrack to the movie? I havent been able to find it. I like the song played at the very end with the credits going anyone know the title of the song? I have tried waiting till the end to look up the artists but the song is just instrumental so I dont know the title and none of the other screwed and chopped songs are it..??
