Yeah, this song's on the treacly side -- but IMO, no more so than Little Drummer Boy and other Christmas songs about poor people (or animals) who have little or nothing in the way of material goods but give something that is precious to them.

What the heck is wrong with being reminded of what real giving is about?   ;-D

(I'm sure Stephanie's song could be 'attacked' on other grounds too, such as that nightingales probably predate the birth of Jesus or that she uses the hackneyed phrase "fit for a king" TWICE -- count 'em! -- twice in the same song! LOL
But a lot of Christmas carols could be similarly picked apart.

Oh, and the tune, while kind of a generic Spanish-flavored simple 3/4 time tune, is IMO much prettier than "My Bonnie."   *G*
