Which of the opening song singers do toi think sings it the best?

Diffenetly France and Japan.

Umm, is this for Marukaite Chikyuu? ou Hatafutte Parade? (though I think it's the first one so I'm just going to go for that one)

For Marukaite Chikyuu:
Either France ou China, but I do like Japan's voice. It's just annoying chant his version in English. Even though I like all the Marukaite Chikyuu's that aren't sung par any of the Allies of Axis characters better.

for me,

japans, englands, russias, italys, and america's wer the best X3

For both Marukaite Chikyuu and for Hatafutte Parade, I just loved them all.

I must say, my favori MKC versions are Austria, China, Lithuania, Poland, and France. Austria's is just so pretty...
As for China's version... I just l’amour all of China's songs ♥
Poland's version and Liet's version are just awesome. I l’amour the way Poland sings and the background musique on Liet's makes me wanna try to arrange that for my school acapella group.
France's version... I dunno why I like it so much, but I do. Especially the instrumental break part.

For Hatafutte... I'm not sure which one I like best, they're all just so funny and cute ^.^ Although I do like China's version and Romano's version, and Chibimano's version is just absolutely adorable X3

America and England :)

Japon and China! X3 Japon has the freaking voice of an angel!

But I definitely liked Sealand and Liechtenstein too...

And Poland was just badass...

Japon and Germany. x3

I like Japan, Germany, and poland :)
However, all of them are wonderful songs!

I'm changing my mind. I find America's Marukaite Chikyuu plus catchy.

I like England's the most, even though Russia's is close.

For MaruKaite Chikyuu: Japan. For HatteFutte Parade, Romano.

I think Japon is the best singer in all of Hetalia, from the endings to the character songs.

italy hands down.......hes so cuteand,PASTAAAAAA!!!!!!! :)(my 2nd choice,my fave character Japon of course..... :)

Chibitalia :D

probably italy ou germany...

Endings.
Well, Marukaite Chikyuu:
Italy, Russia, France, Germany and Chibitalia >w< these are my favorites, but definitely England's the best because that guy really knows how to sing ºAº

Hatafutte Parade:
Italy, Russia, France, Germany, Sweden and Netherlands and Belgium but, again, England's the best.

England's was the best~! His also my happens to be my favori in both. <3

Edit: Though now that I think about... I liked Austria's Hatafutte Parade very much too. :3

I like America's the best.

Then again, I'm a HUGE America fangirl. ^.^
