That's really hard. Only one I'm even remotely sure of is the book. Book: Watership Down Movie: Howl's Moving Castle Song: I Was Born For This by Austin Wintory And really, the song is pretty much impossible. The one I listed is just one that I like at the moment. Ask me in a week and it would likely be something different. Of course, if you asked what my favorites were, you might get different answers. But I do think I could read/watch/listen to these over and over again without getting bored too quickly.
