Faithfully adding to this thread (so that, maybe, if all the things here were combined into a single episode, it would actually make a good movie):
- Numenor anthem song: firstly, that there is one, and secondly, the lyrics are actually appropriate - a land created in the Sundring Sea for mortals, the Land of the Star, etc.
- The Harfeet Walking Song: and in particular the "not all who wander are lost" reference.
