If I have to chose I would pick Hungarian dance no.5 as the song representing Hungary. The composer, Johannes Brahms, was a German but he made 21 dances named "Hungarian". The number 5 is my favorite and reminds me most about Hungary, though the others are really good too.

But there is also other really good songs about Hungary (and in Hungarian). 

I have been writing about our Budapest trip too but I got carried away and it's gonna be a long post so I was too lazy to write it all. I'll finish it later. Hopefully soon.

And other good news: After less than week I'll be in Austria! Going to spend the Easter there.
