Memories of Hetalia (Music): We're Friends, Right?

I'll most likely make a variation of this theme to be the song "We're Family, Right?" Depending on the mood, both songs will probably be interchangeable. I think this is the more "triumphant" variation, though. Hm, just thinking about the friendships between the countries, in Hetalia and in real life. This world we've made.... I dunno, guys. I dunno =)
