Well, if you look at the wiki link in the comments and scroll to Mama Greece's section, there's a link that leade to here: http://hetalia.wikia.com/wiki/Axis_Powers_Hetalia:_The_CD

It just goes by the name of "Axis Powers Hetalia: The CD." And apparently I misread it, as it was released. But it's not an official CD, if I am reading this right. Eh, I don't know. I've honestly haven't heard too much of this anyways. Sorry if I'm confusing/don't make sense.
