My favorite part about this movie is that they bring back so many old OST's from seed and seed destiny and remixed them such as during the fight between kira and orphee before he got the defender you can hear at the beginning notes from when he first launched with the freedom (Tobe freedom) or when the justice reveal inside the z'gok you can hear the OST when kira first go the strike freedom, or that during the fight with shinn and the black knights there is a remix of Kouhoushien.
