I love it too! I wonder if the 3rd Speechless track on the soundtrack (track 12) will be combination of the two parts. I sure hope so!
I managed to transcribe the short version now that we have video with clear sound.
"Here comes a wave meant to wash me away,
a tide that is dragging me under,
Swallowing sand, left with nothing to say,
my voice drowned out in the thunder,
But I won't cry, I won't start to crumble,
whenever they try to shut me or cut me down,
I won't stay silent, you can't keep me quiet,
won't tremble when you try it,
All I know is I won't go speechless..."
"'Cause I'll breath when they try to suffocate me,
don't you underestimate me,
'cause I know that I won't go speechless..."
