A favorite aria?

The lovely arias from Rusalka still continue to drift through my mind. Here is a particularly lovely rendition of "Song to the Moon", which is my favorite aria from that Opera. This rendition seems to have a bit of a Celtic nuance to it. At any rate, I really must make it a point to at some point learn this aria. Perhaps this aria is destined to become my favorite aria to sing? Although I would have to learn how to control my tears as this aria often makes me cry.
