Wheat Field in Moonlight
It doesn't loop perfectly, actually, but that doesn't kill it completely. It's perfect as a song heard only once, which fades out before the end.
I recognize the melody is very, very similar--perhaps dead-on--to The Moonlight Sonata, an excellent classical piece. That is what got my attention the most.
For its intended use and its beauty, I'm more than likely swiping this from the Tower Tactics II soundtrack for a project of my own. IF saying that it's beautiful is one kind of compliment, seriously considering its application in a Flash has to be the best kind of compliment for you, seeing how your efforts won't be wasted.
Excellent work. A second version should loop perfectly, next time.
