User blog:Hetare!Hetalia/The character songs...

I really like to listen to the character songs, and when I'm hearing them, I always go to Hetalia Archives to look for the lyrics. But now I've wondering... do the character songs have any meaning? I mean, if you look at the lyrics of Einsamkeit, you can see a 'story' in it. It's a bit hard to explain, but Let's Boil Hot Water is a song about Italy who loves pasta, you can see that in the lyrics. And I know that you can see it at the titel, but I don't know what W.D.C World Dancing means...

Well, I don't know, what do you guys think?
