Boy, here is an item that doesn't seem to fit in any existing category.

In November, 2009, Enya released a 'greatest hits' sort of album called, "The Very Best of Enya". None of the songs on this recording is new but the version of Aníron is an alternate version from the one heard in the movie or on any LOTR score recording. There are different 'editions' of this album but the version of Aníron is the same on all editions.

The lyrics found in the source text and as sung are similar but different from the movie's version.

You can purchase this single track at various retail mp3 music sites.
