Literally the entirety of Fire Emblem Echoes: Shadows of Valentia's soundtrack is amazing.
Special shoutouts to Twilight of the Gods, Those Who Challenge Gods, With Mila's Divine Protection, Lord of a Dead Empire, March to Deliverance, The Scions' Dance in Purgatory, The Ark of Dawn, Unity, The Sacrifice and the Saint, Sea Winds and Travelers, What Lies in the End, Undiscovered Horizons, The Afterglow Fades, Omen, In a Silver Garden With You, The Course of Gods and Men, A Distant Promise, and The Heritors of Arcadia. And SoV's version of the Fire Emblem Theme.
So there's nineteen songs for y'all to listen to and thank me for later. Hohoho.
