Love it!

Songs I can identify:
* Marukaite Chikyuu (Italy)
* The Delicious Tomato Song (Romano)
* Absolutely Invincible British Gentleman! (England)
* Germany's Anthem (Germany)
* Hamburger Street (America)
* Pub and Go! (England)
* Einsamkeit (Germany)
* The Country From Where the Sun Rises (Japan)
* England's Demon Summoning Song (England)
* Dance of the Trolls (Norway) [Fanmade]

Took about a month after I listened to the Dance of the Trolls to know that it most definitely was part of the medley...

(Just listen to the song, speed up the last part with the medley music in your head, and that might work)
