Hmm...
I can't say it's the BEST song I've heard but I do enjoy it from a sense of nostalgia. The strings clash a bit in the beginning but I think I like that mostly because I grew up on SNES RPG's with that oh so required tower dungeon thing. XD If you're going for that old devilish creepiness sound then I think you've got it! I'd recommend throwing an organ of sorts in there though, that always amps up the creepy factor. All personal opinions mind you. ^_^ Keep workin' hard!!! ^_^
