For those of you who have been trying to find this Ost like i was. Well one of my friends got it and finally put it on Megaupload =]

it is in .rar form so if you have a problem with rar files you have to use such programs as 7-zip or winrar whichever you prefer. I hope this helps anyone and well...ENJOY XD

I heard that this isn't as good as the first Ar Tonelico's music, but I'd like to decide for myself. Thanks!

I'll recommend it. Especially those who liked the first, the music is pretty solid. ^_^d
