I’m a soundtrack maniac. I love, love, love them. Game, anime and movie soundtracks.
How I judged this one was which tracks I listened to the most and never get sick of. Especially that moment when I hear a particular track, I know exactly where I was in a game/anime/movie and it evokes the feeling I had when I was watching or playing it for the first time. It definitely came to Persona 3 & 4, both done by Shoji Meguro (with Atsushi Kitajoh on P4). They have distinct styles and each suit the game really well.
As a personal side note, I use the Persona 3 FES “Burn My Dread” as the ringtone for my partner just because of the feeling it gave me. So whenever he calls, I become happy by hearing it and knowing it’s him.
