From my review of the game, I enjoyed the soundtrack of Final Fantasy Adventure. In no particular order, here are my favorites!
Endless Battlefield: This is Final Fantasy Adventure’s overworld theme. From playing the game, the title of the song really tells a lot about the game. There is an endless amount of enemies, which turns the land into an Endless Battlefield.
Battle 2/Fight 2: Played for the later bosses, and it should be played for the later bosses, because this music makes the battles tenser. The boss battles are already hard enough, and Battle 2/Fight 2 only makes your hands sweatier than before.
In Sorrow- This music just makes the emotional piece sadder. The song tells about the sacrifices made to prevent evil from rising.
