The Return of Sovereign
sounds as if it would make great castle music; like a grand royal castle or wizard's tower.
The "Something Simple" clip sounds as if it could belong to Fire Emblem. Perhaps in one of those short conversations that the characters have between each other. =]Century of Great Battles
sounds as if it could go in a battle museum or historical library. It could even be used during the aftermath of a great battle. =D
I agree with MagitekElite, these audio clips resemble some N64 and SNES games' music. =]
(That is a good thing, since it doesn't resemble them so much that I'd think they were part of those games; they are unique enough to not be construed with the soundtracks of those older games.)
Great work, Spirit_Master_X.
