Put all your angels on the edge
Keep all the roses, I'm not dead
I left a thorn under your bed

I'm never gone

Go tell the world I'm still around
I didn't fly, I'm coming down
You are the wind, the only sound

Whisper to my heart
When hope is torn apart
And no one can save you

I walk alone
Every step I take
I walk alone

My winter storm
Holding me awake
It's never gone
When I walk alone

Go back to sleep forever more
Far from your fools and lock the door
They're all around and they'll make sure

You don't have to see
What I turned out to be
No one can help you

I walk alone
Every step I take
I walk alone

My winter storm
Holding me awake
It's never gone
When I walk alone

Waiting up in heaven
I was never far from you
Spinning down I felt your every move

I walk alone
Every step I take
I walk alone

My winter storm
Holding me awake
It's never gone
When I walk alone

"I Walk Alone" is the first single from the album My Winter Storm by Tarja. This song was written by Mattias Lindblom and Anders Wollbeck. It was inspired by a musical motif in Requiem by Mozart. It features a theater atmosphere accompanied by orchestra, guitars, and Turunen's powerful voice.

According to Turunen the song "describes her personality perfectly well and identifies her as a singer" Some fans have considered this as her response to Nightwish's Bye Bye Beautiful, which was a song directed towards her. The song was a declaration of her independence and willingness to move on.
