-The Planet Namek (Freeza Saga Theme) from Dragon Universe Mode (Not the battle stage.)
-The music that plays when you find an item/Dragonball/random event in Dragon Universe (There are two that I know of, one plays for the lighter-hearted characters, another plays for darker characters like Vegeta.)
-The theme that plays at the beginning of each saga (When the screen with pictures from the show and the DBZ announcer guy starts talking about what happens between sagas. This theme was in Budokai 1, yes but is extended in B3.)
Thats all. If you want me to go more into specifics I can. Thanks to anyone who decides to upload these! ^_^
