Gollum's Song. You may have to be a fan of the book/film to appreciate it:

Where once was light

Now darkness falls

Where once was love

Love is no more

Don't say - goodbye

Don't say - I didn't try...

These tears we cry

Are falling rain

For all the lies

You told us

The hurt, the blame!

And we will weep

To be so alone

We are lost!

We can never go home

So in the end

I will be - what I will be

No loyal friend

Was ever there for me

Now we say - goodbye

We say - you didn't try

These tears you cry

Have come too late

Take back the lies

The hurt, the blame!

And you will weep

When you face the end alone

You are lost!

You can never go home
