Hands down, this ballad by Kate Bush has THE BEST violin solo of any non-classical song. The song itself, though a bit of a downer, is really very beautiful.

"The Fog"

You see, I'm all grown up now.
He said,
Just put your feet down child,
'Cause you're all grown up now.

Just like a photograph,
I pick you up.
Just like a station on the radio,
I pick you up.
Just like a face in the crowd,
I pick you up.
Just like a feeling that you're sending out,
I pick it up.

But I can't let you go.
If I let you go,
You slip into the fog...

This love was big enough for the both of us.
This love of yours was big enough to be frightened of.
It's deep and dark, like the water was,
The day I learned to swim.

He said,
Just put your feet down, child.
Just put your feet down child,
The water is only waist high.
I'll let go of you gently,
Then you can swim to me.

Is this love big enough to watch over me?
Big enough to let go of me
Without hurting me,
Like the day I learned to swim?

'Cause you're all grown up now.

Just put your feet down, child,
The water is only waist high.
I'll let go of you gently,
Then you can swim to me.
