Fullmetal Alchemist: Brotherhood.

The Sopranos.

Futurama

Lots of good mentions. Especially The Expanse and Bluey.

I'd like to highlight the masterpiece that was Andor S1 intros though.

Raised by Wolves, the best intro ever made IMO. And currently Dope Thief, also superb.

Twin Peaks

Surprised I didn't see Evangelion on here (unless I missed it).

What we do in the shadows.

King of the hill.

Bluey.

Suits or Suits LA. Catchy tune

Just finished Tokyo Vice and didn't once skip the intro

What We Do In The Dark.

I'll never listen to the song for no reason on its own, but I'll never skip it either.

WKRP in Cincinnati

The white lotus. I didn't like season 3's theme as much as the first 2's but I still like to listen

Mega Man.

Edit: For real tho, SilverHawks, Thundercats, Galaxy Rangers, and Saber Rider.

Guess how old I am

All of them, I never skip the opening. But my top 5 favorites are

Land of the Lustrous (my most listened to song on YT Music for 3 years running)

Read Or Die

Noir

Akudama Drive

Orb: On The Movements Of The Earth

And for something that isn't weeb shit, Psych

I always like that jazzy intro tune to "The Nanny".

Family Guy

Star Trek Enterprise

And as an italian 90s kid, all cartoons on air in the 2000s

Teletubbies

Lucky Star!

Almost every single show I watch. I'm weird in that I almost never can skip a TV show intro. Only exception I can think of right now is the short continuation of Batman the Animated Series they did just before Batman Beyond since they didn't change the intro to match the show.

Halt And Catch Fire.

Sharp Objects had different intros per episode, but they were all good. My favorite is episode 2.

Also, The Leftovers.

General Hospital, I have life, so I won't even start watching this show.

Money Heist

Raised by Wolves had a great intro theme and art style.

I would list the great Star Trek opening themes, but honestly they are long and can be a bit much when you're on your like eighth episode in a row.

ER.

Granted I haven't watched ER since it was on TV in the 90s, but I have gone out of my way to hear that glorious theme song so many times!
