Best Anime Original SoundTrack? (OST)

What’s your favorite?

Not quite anime, but the OST of the Umineko visual novel is God Tier. Some songs:

• Ricordando Il Passato
• Worldend Dominator
• Dreamend Discharger
• Mirage Coordinator
• Happiness of Marionette
• Fishy Aroma
• The Executioner
• Golden Sneer

And those are just 8 out of 100+ songs form the VN.

Another candidate is the OST from the "97 Berserk anime. Susumu Hirasawa is a freaking genius, what can I say.

• Forces
• Guts
• + Aria from the movies and Hai Yo from the 2016 anime (the only good thing from that anime)

Can't post links since I'm one my phone but,

Kino Journey

Wolf Rain

Cowboy Bebop

Soul Eater

Samurai Champloo

Ghost In The Shell

I always find myself listening to the OSTs for Code Geass, Hajime no Ippo and Gundam Wing.

Geass:

The Master, Avalon, Nightmare, Boy from Britannia, All Hail Britannia, Elegant Force, Love is Justice, Blue Tiger, A

Wing:

Wufei's Irritation, Eternity & Infinity Are In These Hands, Unknown Pressure, Legend of Zero, Swinging Target, As Relena Peacecraft, Who Will Give Their Life to Burn?, Sandy Clock of a Sad Color aka Hourglass of Sadness (the piano part that hits at 0:53) is almost indescribable).

Ippo:

Stand Proud, At Last, Inner Light, and more. Also, the first ed is the perfect ED to me. It ratchets down the excitement of the episode and almost forces you to reflect on the previous episode's story.

.

Wing and Geass' OST are highly varied ranging from synth and electric guitars to castanets and violins.

Geass did an excellent job with insert songs like Stories as well.

Cowboy Bebop/Samurai Champloo

Faulconer

Code Geass

Fullmetal Alchemist (specifically Brotherhood)

Cowboy Bebop

Soul Eater

Bleach

Kill la Kill

Nanatsu no Taizai

Yu Yu Hakusho

These are the ones that come in mind.
