Long time no music!
It's no secret anymore, but I totally love ambient music!!
And this is actually pretty good too. It's simple, but that is precisely what gives it this creepy feel. This would be perfect background music for a game, especially an MMORPG of some sort, when in a darker area (nighttime, by a graveyard, in a cave setting, etc). The sound quality is nice too, or so my expensive headphones tell me.
Only thing I'm going to criticise is that the loop could probably be a bit more smooth :p
Easy favorite, great job ;)
