Favourite song sung in the movies

[Caladarasiel]

Well I personally like Gollum's song and the one Pippin sings in RoTK, but a song that is not in the movie that I like is the one Legolas sings in RotK
Legolas's Song of the Sea
To the Sea, to the Sea! The white gulls are crying,
The wind is blowing, and the white foam is flying.
West, west away, the round sun is falling.
Grey ship, grey ship, do you hear them calling,
The voices of my people that have gone before me?
I will leave, I will leave the woods that bore me;
For our days are ending and our years failing.
I will pass the wide waters lonely sailing.
Long are the waves on the Last Shore falling,
Sweet are the voices in the Lost Isle calling,
In Eressëa, in Elvenhome that no man can discover,
Where the leaves fall not: land of my people for ever!
