I do quite like the 1st ending song of Attack on Titan / Shingeki no Kyojin;
Beautiful cruel world / Utsukushiki Zankoku na SekaiLyrics:
That dream is where my heart belongs,
and it's something more fragile than my life.
Again and again, I abandoned and then rediscovered it.
Now sleep peacefully.
With my wish being ravished by my pounding heartbeats,
as soon as I'm on the verge of forgetting it, I immediately recall it.
In this beautiful cruel world,
we merely keep on asking "why" we're alive and living...
Ah, with this strength and this weakness,
if we no longer possess any rationality,
just what are we protecting?
Isn't that sky depressing?
The ashes and mirages swirl up in the sky.
Freeze solid to the warm words,
now sleep discreetly.
With my sigh being hid away by my clingy fantasies,
as soon as it's about to break free, it's pinned down again.
In this beautiful cruel world,
we merely keep on begging death to wait a little longer...
Ah, no different from the flightless weathercock,
we will not understand
whether truths are prettier than lies.
If only we were songs,
we would be able to sail at full speed in the wind,
and bring hope without fail
to someone out there.
In this beautiful cruel world,
we merely keep on asking "why" we're alive and living...
Ah, with this strength and this weakness,
if we no longer possess any rationality,
just what are we protecting?
While at it,
Sayonara Zetsubou Sensei / Goodbye Mr. Despair one of the openings, unfortunately not full version, just the 1:30 OP.
Edit:
Found the full version, yay.Lyrics:
"Warped, warped, warped, warped" *4 (or twisted as in the video)
I was watching the TV late at night
I had nothing to do so I was just watching it absent-mindedly
Flipping through channels, successful people were getting recognition
"That person isn't warped at all... how wonderful"*
"How boring," I thought and turned it off
Better go to sleep, I have work from tomorrow on
Unable to go to sleep, I flipped through some comics
A gravure idol was smiling at me**
"That athlete is just my type.
Those sorts aren't warped at all... how wonderful"
I get it, the reason I'm not rewarded
Is because, as a person, I'm quite warped
So sit up properly! Already,
I'm warping, warping, warping away
Make it so I can't tell why I'm trembling!
Slipping away! I'm already a warped human
But if you are here, I can change?
"Just realize that I am here"
Think of the warping as a surge
Won't this warping change the world as well?
I feel people can't help but notice me
Even if now they can only see me trembling
Alright, I get it, the reason I'm not rewarded
Is because, as a person, I'm quite warped
Ah, I get it, the reason I'm trembling
Is because I don't have anyone to support me
I'm sitting up! Already,
We're warping, warping, warping away
Make it so I can't tell why I'm trembling!
Slipping away! I'm already a warped human
But if I meet you, I can change?
"Just realize that I am here..."
