If the album was purchased in Canada, "Walk In", "Inside" and "Walk Out" are recorded on a different instrumental, with slightly different lyrics. Also, "Earthquake" is replaced by the song "Crack Ya Bottle" by Lil Wayne featuring Reel, produced by the Architects. These changes are a result of sample clearance issues.
