I've sometimes been known to say that in a perfect world we'd all trade in English, woo in Spanish, and sing in Finnish.
In a sense it's nothing special -- a pop song, albeit a very popular one, about being far away from the one you love. Someone with a good voice could sing a Finnish phone book and it would be stunning, and this is rather better than a phone book, and Vartiainen is much better than merely a 'good voice'. But good voice or not, why would anyone with a language like this do anything but sing and write poetry? I honestly don't know; almost everything else would be a waste of time.
