Something I just noticed
In all the times I've seen this I just hit upon something. I may be reading too much into it, but I'm not sure. In the very beginning we hear what sounds like an angelic choir singing HARK! THE HERALD ANGELS SING as the picture goes from up in the stars down to earth and a group of children singing the same. Some are out of tune, loud, etc. Could this be saying that to the ears of God the pure hearted singing of these children sounds just as the angels would? Just a thought.
When it comes to pain and suffering, she's right up there with Elizabeth Taylor.
