Have you played the Great Language Game? It's been making its way around the internets lately and I finally gave it a try yesterday. You listen to a clip of one of 80 languages and given 2 - 5 language choices, try to make the match.
I'm terrible! My best score was 500, which translates to 10 correct answers and 3 incorrect ones (after which you run out of "lives"). I got more of them through process of elimination than by actually recognizing the language.
And side note: I took four years of German classes and can identify it easily, so of course I wasn't presented with any German clips. grumble grumble. :)
I want to hear your score if you try!
