Post one of your yêu thích anime soundtracks

There are many really good soundtracks that I like
And Shingeki no Kyojin is one of them

I would say Sword Art Online~

Guilty Crown definitely!
I like Code Geass and Durarara's also

Death Note's soundtrack is insanely epic.

Bleach (though not one of my yêu thích anime, I think it has the best OST)
Code Geass
Attack on Titan
Guilty Crown
