I personally love „Life will Change“ (both instrumental and with lyrics) but i kinda see new old songs from the whole series so it‘s very hard to decide but shadow world best intro imo

Wiping all out will always be one of my most fav, Dancing all night made me love A deep mentality the lotus juice remix a lot though. So overall P3s music is fire to me. My first favourite in the whole series was Laser beam because PQ was my first game to get me into the series.

If youre asking about the message ill say 'Ill face myself' cause I can totally relate to that and it reminds me of my childhood since I was very shy that time. If its about the music itself it would be 'never see it coming' cause it is super catchy and it makes my blood boil everytime I hear it

I really like P3 FES, the opening to (believe it or don't) P3 FES. (the OP itself isn't as good as P3, but the song is better imo) https://www.youtube.com/watch?v=lGjPut-k-7U i also like the OP for PQ2, road less taken https://www.youtube.com/watch?v=_GSuWkZ3kms and then life will change and whims of fate

"Fate is in our hands" from the Persona 3 Movies. Freaking love that song. Also all renditions of Burn My Dread, I love "Maze of Life" and "Road Less Taken" from the Q subseries, Life will Change and Swear to my Bones are other persona-l favorites of mine as well
