so Umaga's theme and King Booker's theme, much like many wrestler's themes, are stock music. You can purchase different versions from libraries, but typically a full version, a 90 second version, a 60 second version, a 30 second version, and a "stinger". In Umaga's case, I think the team was unaware that WWE made an edit themselves of "Virtual Voodoo", and just purchased the full version instead of getting the theme itself from WWE. In King Booker's case, I think it was out of laziness, they didn't check to see which version they licensed, and accidentally grabbed the 30 second version.
