I really love the opening and ending themes of Abaraka: The Crimson Flower That Divides (越えざるは紅い花). The opening theme shares its title with the game, while the ending theme is titled Eien no Na (The Eternal Name). The songs carry a strong exotic flair and fit perfectly with the game's setting and themes. I used to have them on repeat quite often during my car rides.
