In honor of Larry "Chipper" Jones announcing his retirement at the end of the 2012 baseball season our "It's Friday!" song is Ozzy Osbourne's "Crazy Train."
If I am not mistaken, Chipper has also used Trick Daddy's "Let's Go" as his music. Of course it samples "Crazy Train" and contains a lot of NSFW language.
