Cohen is considered a poet more than a singer; something like Dylan. Cohen, however, can tend to be crude and lustful in his lyrics. I can't say that I agree with his perspective but when put to music, I like it.
This first one is pretty tame.

LEONARD COHEN LYRICS
"Anthem"
The birds they sang
at the break of day
Start again
I heard them say
Don't dwell on what
has passed away
or what is yet to be.
Ah the wars they will
be fought again
The holy dove
She will be caught again
bought and sold
and bought again
the dove is never free.

Ring the bells that still can ring
Forget your perfect offering
There is a crack in everything
That's how the light gets in.

We asked for signs
the signs were sent:
the birth betrayed
the marriage spent
Yeah the widowhood
of every government --
signs for all to see.

I can't run no more
with that lawless crowd
while the killers in high places
say their prayers out loud.
But they've summoned, they've summoned up
a thundercloud
and they're going to hear from me.

Ring the bells that still can ring ...

You can add up the parts
but you won't have the sum
You can strike up the march,
there is no drum
Every heart, every heart
to love will come
but like a refugee.

Ring the bells that still can ring
Forget your perfect offering
There is a crack, a crack in everything
That's how the light gets in.

"Hallelujah"
Now I've heard there was a secret chord
That David played, and it pleased the Lord
But you don't really care for music, do you?
It goes like this
The fourth, the fifth
The minor fall, the major lift
The baffled king composing Hallelujah
Hallelujah
Hallelujah
Hallelujah
Hallelujah

Your faith was strong but you needed proof
You saw her bathing on the roof
Her beauty and the moonlight overthrew you
She tied you
To a kitchen chair
She broke your throne, and she cut your hair
And from your lips she drew the Hallelujah

Hallelujah, Hallelujah
Hallelujah, Hallelujah

You say I took the name in vain
I don't even know the name
But if I did, well really, what's it to you?
There's a blaze of light
In every word
It doesn't matter which you heard
The holy or the broken Hallelujah

Hallelujah, Hallelujah
Hallelujah, Hallelujah

I did my best, it wasn't much
I couldn't feel, so I tried to touch
I've told the truth, I didn't come to fool you
And even though
It all went wrong
I'll stand before the Lord of Song
With nothing on my tongue but Hallelujah

Hallelujah, Hallelujah
Hallelujah, Hallelujah
Hallelujah, Hallelujah
Hallelujah, Hallelujah
Hallelujah, Hallelujah
Hallelujah, Hallelujah
Hallelujah, Hallelujah
Hallelujah, Hallelujah
Hallelujah
