Answer 1

Games can tailor the volume of the sound track to the events within the game. Look at the most recent Doom game and you can see that the metal music is synchronized to the player and will change due to their activity. In the games you reference they may desire to increase or decrease the volume based on the scene but not know where in the soundtrack it will be at the time.
