Seaons 2 Finale Help

Please help me.....I know everybody asks about song information, but hopefully someone will help me out here. At the end of Season 2, Episode 8, "New Cars" there is a hispanic rap song playing when BIG breaks out Rob's C-List jacket and the song continues on through the credits. What is the name of that damn song, or even if it's an instrumental I would love to know so I can use it on a project for school. I cannot find the song name anywhere for the life of me. I've been looking on the internet everyday. This song would fit perfectly for my video project for school. HELP ME PLEASE!!!!!

Thanks, Jon
