I could easily post 100+ tracks from FFXIV, unquestionably one of the strongest and most diverse soundtracks in all of gaming, but rather than post the ever present Answers or one of the more hyped/boss tracks (Steel Reason, To the Edge, A Long Fall ect), I will point to A Mother's Pride
I used to listen to this while spearfishing in Yanxia (and it sounds even more magical underwater since there's an extra couple of violin/cello notes thrown in that really add to it) but the night themes of FFXIV are some of the most hauntingly beautiful stuff you'll find anywhere. It's a freaking lullaby for the soul
