OST from the final scene

The last music we hear in the anime is called "Crybaby". This is played when Satan and Akira look at the sky full of stars when the planet is totally destroyed. I need to say that this OST is one of the purest and saddest music I've ever heard. I can't even describe it. Every time that I hear the first notes of the melody, my eyes start to tearing up. I like to listen to it when I look at the stars at night, and I feel like Satan and Akira are next to me, and that we are together looking peacefully at the starry sky.
