Got to say, the boss fight with Noah has become one of my favourite final bosses in gaming and it's not just because of the music. It's because you legitimately have to use all of your skills to survive, and the ending blow against Final Noah Prime with all of your legions is purely epic. (The fight against the core is admittedly a slight let-down music wise though, I mean it starts off good with Soul of Ambition with the choir but then the core fight OST lets it down but then the music for Noah Prime just redeems it with a masterful melody that perfectly conveys how much of a threat Noah Prime really is).
