Okay, so this song is called "Swan Song", which though I'm sure most of you know what the phrase means,
you can look here if you don't. The use of the phrase is pretty evident in the context of the song, though.
Swan Song"Swan Song"
There’s a little girl
In a little world
Every single day
There’s a smile on her face
There’s a little girl
And she always loves to sing
When she sings her song
All the angels sing along
Na na na na na
Na na na na na
Na na na na na
Na na na na na
Na na na na na
Na na na na na na na
Na na na na na
Na na na na na
Though as time goes on
When her smile’s gone
Every single day
Is another pain
And so every night
When she’s hiding from the light
She will sing her song
And the angels sing along
Na na na na na
Na na na na na
Na na na na na
Na na na na na
Na na na na na
Na na na na na na na
Na na na na na
Na na na na na
The pain gets too much
The attack’s too rough
They went overboard
And the girl’s no more
Now in Heaven’s light
She’s an angel in the sky
So she sings her song
And the angels sing along
Na na na na na
Na na na na na
Na na na na na
Na na na na na
Na na na na na
Na na na na na na na
Na na na na na
Na na na na na
So she sings her song
For the ones done wrong
Every time she sings
They all sing along
She sings a swan song
For the children that are gone
You can hear them sing
And the angels sing along
Na na na na na
Na na na na na
Na na na na na
Na na na na na
Na na na na na
Na na na na na na na
Na na na na na
Na na na na na
My inspirations for this song would probably be a mix of Concrete Angel and Whiskey Lullaby (if any of y'all listen to Country), so be prepared for a tear-jerker!
, I have to search hundred pages back in MC base
