Please don't forget that this is an alpha version, that's like even earlier than beta. Most of the game is not complete. The amount of options there currently are in character creation do not in any way reflect the amount of options you will get when the game is complete. The game's performance is not as good as it will be in the final game either, nor are the graphics as good looking as they will be later.
What exactly do you mean by theme tune? The one that's been around since Final Fantasy 1 and used in something like half of all the games in the series? :p
The main reason Square Enix doesn't want alpha test leaks is people jumping to conclusions like this, based on something that is "work in progress" :p.
