"Message In A Bottle" has a guitar outro with extra vocals that is not in the master track.
In the XBOX 360 version, a note at the end of the credits reads "No pitchers were harmed in the making of this game. Except for one. Joel Zumaya. He had it coming." Zumaya had actually injured himself playing Guitar Hero, and ended up unable to play in the 2006 American League Championship Series.
