You are joking, but the soundtrack to httyd is considered as one of the most influential classical orchestra creation of our time. With the amound of motives repeating across the whole movie where each motive has multiple variants depending on the plot of the story we are talking about a full 2 hours long symphony that holds a story on its own. If you have seen the movie before, give it a listen as a whole and i guarantee you that you will be able to keep up storywise just by listening to the soundtrack.
