Feanor's marching song (lyric accompanying the Sacred War, Russian Red Army Choir; a sample can be found on youtube watch?v=maYCStVzjDs)
Disclaimer: the Silmarillion belongs to the Tolkiens and the Sacred War belongs to its author. I have no right to do whatsoever I am doing now.
Arise, the mighty Noldor, to march to homeland.
By lies and false promises, you have lost too much.
Let your righteous anger burn and cry revenge for all,
when your king have died defending light, lights that now are gone.
Let ancient callings waken and lead you back to stars,
where rivers run in lush lands, and freedom levels all.
Will warnings hold up your steps? Will honor be forfeited?
Take no heed of your wealth of burdens - for more we are to make.
Arise, the mighty Noldor, to march to homeland.
What are these losses to us, but a sign to start anew?
Let your righteous anger burn and cry revenge for all,
then we may dance again in happiness, for ages to come.
AN: Basically a rephrase of his words. A friend said old Russian Army songs suit the Nolofinwians, but I think this particular one feels more like Feanor's type... It is very strong.
Probably boring, but anyway.
