Forum:The Song of Eldamar

In the Fellowship of the Ring book 2, chapter 8 (Farewell to Lórien), whilst the fellowship itself was in boats already, Galadriel who came down the river on her Swan-boat sang a song - the Song of Eldamar [as named in the index]. Why isn't this song (a sonnet actually) Included in the "Songs and Verses" page (http://lotr.wikia.com/wiki/Songs_and_Verses)???
