(edited) The song is "the unfrogiven" but in the song he says i dub thee unforgiven. In the song he is talking about him growing up and about all the things that people did wrong to him and expected him to do. he tries to please every1 but cant and is forced to fight a batltle he cannot win. They(whoever "they is") labled him as always doing things wrong and as he grew up he never forgave them thus the line "I dub thee unforgivin". Metallica's lyrics are not just other american songs that are used to just make stuff rhyme and ne1 that has ever head a Metallica song will agree with that. Just for proof here are the lyrics to the song:
New blood joins this earth
And quickly he's subdued
Through constant pain disgrace
The young boy learns their rules
With time the child draws in
This whipping boy done wrong
Deprived of all his thoughts
The young man struggles on and on he's known
A vow unto his own
That never from this day
His will they'll take away
What I've felt
What I've known
Never shined through in what I've shown
Never be
Never see
Won't see what might have been
What I've felt
What I've known
Never shined through in what I've shown
Never free
Never me
So I dub thee unforgiven
They dedicate their lives
To running all of his
He tries to please them all
This bitter man he is
Throughout his life the same
He's battled constantly
This fight he cannot win
A tired man they see no longer cares
The old man then prepares
To die regretfully
That old man here is me (this is where he says that this song is about him)
What I've felt
What I've known
Never shined through in what I've shown
Never be
Never see
Won't see what might have been
What I've felt
What I've known
Never shined through in what I've shown
Never free
Never me
So I dub thee unforgiven
You labeled me
I'll label you
So I dub thee unforgiven
