Correct heres the full instrumental.55:26 - 55:36 is a sample from the song:
"I'm so hood" by G-Unit. Album is "Beg for mercy".
Funny that they would put that song.

The song was recorded from the itunes music store preview. I apologize for the large file size (its about 5 MB). I could post a smaller version or see if I can find an online site to preview this music.
