I agree...While the Gargoyles don't bother me like they do many other people,the happy,upbeat tone of the song just felt so out of place in the film,especially considering what was going on outside of Notre Dame at the time (Frollo rounding up all the gypsies he could find,in his search for Esmeralda,plus his burning down of the home of a family who was harboring gypsies)....
...I like "Court of Miracles" though....both the music and the lyrics..
I liked the songs in Mulan as well ("Reflection" is one of my favorite Disney songs,and I love the animation that goes along with it),though to be fair,I think the movie could've worked just as well without songs...
