I'd first like to credit Underworld23, whose own Top 100 Battle Themes Playlist I viewed in its entirety. However, I couldn't help but think the entire time how much I disagreed with the list, no offense to Underworld23, of course. So I decided to take this cool idea on myself. And now we have my take.
Regarding the music chosen in this list: In the case that a theme appears in multiple games, I chose the version I preferred; All the music in this list is represented as it is heard in the game (no arrangements); Music from action RPGs are included at my discretion (as in, what I consider to be either an action RPG or an action/adventure game avid RPG players are likely to play and/or enjoy for the same or similar reasons they would any other RPG).
100 ~ Fefnir (Ar Tonelico) 99 ~ Felix Battle Theme (Golden Sun: The Lost Age) 98 ~ An Enemy Appears! (Lost Odyssey) 97 ~ Last Battle (The Legend of Zelda: Ocarina of Time) 96 ~ Fragments of Soul (Legaia Duel Saga) 95 ~ COMBAT 1 (Grandia Xtreme) 94 ~ J-E-N-O-V-A (Final Fantasy VII)
