A nice story of strength...

Silent, I can't wait here silent
Working up a storm inside my head
Nothing, I just stood for nothing
So I fell for everything you said

Hear the rumble
Hear my voice

Silent, I can't wait here silent
Gotta make a change and make some noise

Undo my sad
Undo what hurts so bad
Undo my pain
Gonna get out, through the rain
I know that I am over you
At last I know what I should do
Undo my sad

Trouble, baby I'm in trouble
Everytime I look into your eyes
Save me, oh I'm gonna save me
Far away from all the crazy lies

Hear the rumble
Hear my voice

Undo my sad
Undo what hurts so bad
Undo my pain
Gonna get out, through the rain
I know that I am over you
At last I know what I should do
Undo my sad

Undo my sad
Undo what hurts so bad
Undo my pain
Gonna get out, through the rain
I know that I am over you
At last I know what I should do
Undo my sad

My sad love undo

SILENT= Without sound.

WORKING UP= To develop or produce by mental or physical effort; in this case a storm inside her head.

RUMBLE= A deep resonant sound.

GOTTA= (Informal) Contraction of '(have) got to' = must.

MAKE A CHANGE=  To grow or become better by reforming oneself.

MAKE SOME NOISE= To attract attention. To do something noticeable.

UNDO= Lead to downfall, destroy.

MY SAD= This doesn't make any sense, because SAD is an adjective and here it is used with a possessive adjective, like a noun. In fact we here "my sad" many times through the song without knowing what is the sad thing she is talking about, because every time she's going to say it, the sentence stops. It is only at the end, the last line, when we hear the complete sentence: MY SAD LOVE.

PAIN= Suffering.

GET OUT= To leave or escape.

I AM OVER YOU= I've moved on (if used at the end of a relationship). It means that at one time I had feelings for you , but now those feelings are gone and now I am indifferent to them or at least not trapped by them.

AT LAST= Finally.

I'M IN TROUBLE= I'm in difficulty, in affliction.

FAR AWAY FROM= At a distance.

Sanna explains that 'Undo' is about many things. It is up to the listener to decide what exactly it means to them. The first thing you think about is that it is about a relationship that is not very good and you really want to be in a better place, but I think it is important to know that there still is hope. It is not bad all the time. You have the strength to do something about it.
