Excalibur has repacked the full Granado Espada OST for everyone, and you can dowload it here.
For those who hates the English voices to the core, you can also download the jGE voice pack which will change all your character voices to hot japanese seiyuus like 田中理恵 (female Warlock), 置鮎龍太郎 (male Wizard), etc.
Download them, extract them to your program files/granado espada/ge folder. You will replace a file call the ‘se.ipf’. Back that file up if you want to. So far it has not caused any problems with the game at all so there is no real need to do so.
