I think Mumford and Sons are quite therapeutic!

Check out "The Cave"

T says:
It's empty in the valley of your heart
The sun, it rises slowly as you walk
Away from all the fears
And all the faults you've left behind

The harvest left no food for you to eat
You cannibal, you meat-eater, you see
But I have seen the same
I know the shame in your defeat

But I will hold on hope
And I won't let you choke
On the noose around your neck

I say:
And I'll find strength in pain
And I will change my ways
I'll know my name as it's called again

Cause I have other things to fill my time
You take what is yours and I'll take mine
Now let me at the truth
Which will refresh my broken mind

So tie me to a post and block my ears
I can see widows and orphans through my tears
I know my call despite my faults
And despite my growing fears

T says:
But I will hold on hope
And I won't let you choke
On the noose around your neck

I say:
And I'll find strength in pain
And I will change my ways
I'll know my name as it's called again

T says:
So come out of your cave walking on your hands
And see the world hanging upside down
You can understand dependence
When you know the maker's land

I say:
So make your siren's call
And sing all you want
I will not hear what you have to say

Cause I need freedom now
And I need to know how
To live my life as it's meant to be

T says:
And I will hold on hope
And I won't let you choke
On the noose around your neck

I say:
And I'll find strength in pain
And I will change my ways
I'll know my name as it's called again

Also, a song that has captivated me is "Have You Forsaken Me?" by The Brilliance. Beautiful instrumentation (although not terribly therapeutic)!

The lone lyric over and over:

My God,
Have You forsaken me?
Forsaken me?
Forsaken me?
