I was watching Frozen II at the cinemas the other day, and I was listening to some of the background music, and I'm pretty sure that I heard Franz Liszt's 12th Transcendental Etude in some of it. It was especially prominent in the scene where (SPOILER)
Elsa was putting out the magical fire in the forest with her ice powers
but I can't find the scene online in order to confirm my thoughts yet. If anyone could be able to help it would be appreciated.
