Swedish, by far. maybe i'm biased though, the girl is from there...
i love the sound of the swedish language too, some of their words have exactly the same spelling, but are pronounced with two tones giving two different words! the tone is falling after the first part of the word and raising on the second half. if you say the word with one tone, it means something completely different and you have to look at context (when read) to see which word it refers to! (bizarre!) it gives the language a kind of sing-song sound. very sexy...
