I am actually a quarter Estionian, but my Eesti Keelt is mostly limited to talking about vehicles and car decks, due to work. Many people think Estonian and Finnish are pretty much the same, which isn't true; they do have lots of similarities, but just by knowing one of them does not mean you will get by on the other (like Swedish and Norwegian for example, where you understand pretty much of the other, at least on a basic level).
Well anyway, this song is called laughter; he sings about sumer ending and the could autumn wind's laughter.
You can hear all of the Soft Sunday songs on my frequently updated Spotify list; although not all songs can be found on youtube or vice versa, not on Spotify, so this song had to compromise.
Oh, and also, you still have one more day to enter my New Year's Best of 2010 give-away, I will end it tomorrow!
