What anime will you never skip the theme on a rewatch?

Any anime. The songs are part of the story.

Mob Psycho season 1. It's just amazing. Also, Barakamon.

Eva and Bebop

Pokemon, the OG. I'm also loving all the cowboy Bebop. Also couple seasons of FMA are straight up bangers!

Ranma 1/2 natch

Evangelion, pretty much all the FMA:Brotherhood ops, School Rumble, and Jellyfish Princess.

First season of Vinland and Steins;Gate

• Btooom!: Probably the best part of the show was the op lmao
• Code Geass R2: I actually think op4 and 5 are the best from code geass, and I didn't like op2 from r1
• Ga-Rei: Zero: Awesome show, awesome song
• Happy Sugar Life: Like melting Madoka Magica's op and ed together
• Houseki no Kuni: The show is extremely good, and the op itself conveys its atmosphere.
• Kiss x Sis OVA: The op and the ed are both good in different senses
• Kiss x Sis tv: I don't like the op, but the ed is pretty good.
• Madoka Magica: op and ed are polar opposites
• Mirai Nikki: (Show bad, op good) ^ 1000
• Noragami Aragoto: We all know that one.
• Shiki: Mainly the ops and eds that BUCK-TICK composed
• Shinsekai Yori: The first ed is pure and fine art.
• Steins;Gate
• Toradora: I hated op1 at first (and i repeated op2 again and again a month after toradora cuz i couldnt get over it)
• Yosuga no Sora: lmao

The end theme for black lagoon still occasionally gives me goosebumps, I think it’s how atmospheric it is and somewhat calm/sad after the chaos of a typical BL episode. That I never saw the end of the outro until my second watch and always assumed it was her walking to her death after a firefight.

Witch Hunter Robin.

Definitely Jujutsu Kaisen same as the outro way too catchy.

And even though it's a Netflix anime, Super Crooks what a hot banger of an intro!

Re:Creators' first theme gravityWall, is great.

Hellsing (2001).

Yuyu Hakusho

Digimon from S01 to S03.

And many from Naruto and Naruto Shippuden.

I've liked a lot of openings but usually end up skipping eventually, the only one I can think of I wouldn't was Death Parade, it's too much of a banger

OG Dragon Ball

Sayonara, Zetsubou-Sensei has some bangers.

All of them. I only watch shows with absolute banger openings

There are a few that transcend that, and became the reason I would watch multiple episodes at a time. All intros for Steins;Gate, Durarara, Kaguya-sama, and Nichijou are the best of the best

Just off the top of my head...

Cowboy Bebop, Kekkai Sensen S1, Durarara, SSSS Gridman, Death Parade, Jojo 2nd

EDs: Samurai Champloo, SpyxFamily, Kekkai Sensen, any psychological/philosophical show (like Psychopass and Death Parade) because I'm having a wtf moment anyway and need it to wash over me.

Gintama Pray and Donten

I'll admit to skipping most after a few episodes or if I'm in a marathon, but I love the intro to Vivy, don't think I ever skipped that one, nor will I when I rewatch that..

Made in Abyss because again, the music is awesome (big Penkin Fan), Bepop and Champloo I tend to watch every time too. there are probably tons of others but I cant remember everything cause my brain is mostly made of mud these days.

Hozuki's Coolheadedness, and Ergo Proxy.

Steins Gate, Psycho Pass, Tokyo Ghoul, FMA, Death Note, Cowboy Bebop, Space Dandy, Vinland Saga, Soul Eater, 91 Days, 1st OP of Food Wars, and I’m sure a few others I’m forgetting.

Code Geass almost makes the cut, but I usually end up skipping it eventually.

Edit: Oh, and most of the JoJo OPs.

Polar bear's cafe (shiro Kuma cafe). Niche but great! Also super wholesome
