What TV show has your favourite original soundtrack, or use of music?

Cowboy bebop is awesome.

RWBY's OST has no business being as good as it is.

The Mandalorian OST is great too.

Also a mention for One Punch Man OST, specifically Genos's theme, my man looks like a total badass and his theme really complements the fights right up until he lets his guard down and gets flattened every fucking time.

Mr. ROBOT and Westworld have some amazing scores aside from the cover versions they provide.

The various versions of paint it black are fucking fantastic.
Mr Robot's soundtrack is awesome, I remember the agonizing years waiting for the final volume to come out through all the red tape
Absolutely worth it

Battlestar Galactica! All of the themes for the various characters fit really well, and the taiko-style drums during space battles, which at first might seem stylistically a bit strange, work amazingly well to amp up the sense of urgency.

The drums add crazzzzy tension to those battles and totally capture the "Well, I guess now we have to wait a whole 45 seconds before that giant salvo of missiles we can all see clear-as-crystal closes in another 2 clicks towards our position and absolutely nukes us" vibe of it all.
I've always thought that BSG's combat scoring was influenced by the combat music from the OG Homeworld game, which itself is ultra loosely based on the 70's BSG show.
I loved their version of "All Along the Watchtower"

Twin Peaks. Lots of mood. The revival had several musical guests, too.

Angelo Badalamenti is super talented 🎶

Samurai Champloo has a good soundtrack.

Scrubs

I liked the ukulele songs about all the states.

Peacemaker Season 2 opening
Adventure Time closing
One Punch Man Season 1 closing

Peacemaker Season 1 Opening
and an honourable mention for James Gunns other show Creature Commandos - all that punk and especially that Romani punk.
God knows I've had some rough fucking years!
I always listen through the Adventure Time ending. The only thing that ruins it is the production company messages at the end that cut the song off abrubtly.
- You can find the complete version of adventure time's ending song. It's called island song :)

I really like the theme song and musical setting of Firefly. I'm not as hyped about the story now as I once was, but the music is still great.

The Taskmaster intro always hypes me up for every episode

Also the Curb Your Enthusiasm theme could not fit any more perfectly. To this day every time I see the static noise before any HBO show I expect to hear "bum Bum BUM daaaaaaah..."

That's Alex Horne's band, "The Horne Section" in case you weren't aware
- The theme itself is ‘Frolic’ by Luciano Michelini, composed in 1974 for the film ‘La bellissima estate’ and used since then in some advertisements, in which Larry David had heard it. ‘Curb’ generally uses several old ‘production music’ pieces, i.e. those from a music library for films, tv and such. ‘It's Always Sunny in Philadelphia’ also does this.

Probably Michael Giacchino's score for the show Lost. I felt like I was watching a movie. If we're talking about anime, then Evan Call's score for Frieren: Beyond Journey's End

It’s old but for a long time The Wonder Years supposedly couldn’t be released on home video because there were so many music licenses to get clearance for.

I wish they kept doing shows like that. Every ten years, try to make a decent, smart, earnest show about teenagers living twenty years prior.

Freaks and Geeks

The opening theme to “Taxi.”

WKRP in Cincinnati

Black Sails

Never skipping that intro.

The Drew Carey show

Livin in sin with a safety pin 🎶

White Lotus. The opening themes are all incredible, but all the background music perfectly sets the tone in every scene. Most of it is done by Cristobal, who apparently has had "creative differences" with the show's creator for the show's first three seasons. He's had enough arguing and won't be returning for the fourth season, which is honestly enough to make me skip it despite liking the show.

Exactly
Cliff Martinez does pretty good soundtracks, they even play on ambient radio stations sometimes. I remember his name ever since Solaris.

The criminally underrated Terminator: The Sarah Connor Chronicles had some absolutely gorgeous music. As an example, I think “Sarah Connor’s Theme” is achingly beautiful: https://youtu.be/sJk8BjEkmx0

Really fit the series, too which, while not being short of wit and action, always had a seriously melancholy undercurrent.

I like shows that consequently and (almost) exclusively use actual songs made by real* artists. I remember Orange Is The New Black doing this. And The Wire. Russian Doll. Borat. The list is long.

I prefer shows that do not have a constant mood-setting musical soundtrack.

a little debatable if their only known the track is the one from the show

Max Richter and his score for The Leftovers is great.

Second someone else mention Westworld, which is the same composer as GoT: Ramin Djawadi

There's others I very much enjoy but these two are worth commenting

The Blacklist had a pretty dope soundtrack.

Edit: definitely not "original" music though.

Utopia (the original british series) has a fucking amazing score.

Best use of music has to be Supernatural for sure

https://youtu.be/Y8uMvUgnpwI

Clannad - Robin (the Hooded man) from Robin of Sherwood

Utopia Highly recommended!!!

It wasn't a great show but the anime Kubikiri Cycle had a very interesting soundtrack, composed by Yuki Kajiura. Some examples:

Let Him Tell His Story
Old-fashioned Fairy Tale (this one features her own language)

Kajiura Yuki always was one great compositor. I think she really nailer Tsubasa Chronicles.

enterprise, before they had a wierd people singing.

RWBY has an absolutely beastly original soundtrack

The first season of American Horror Story.

The opening theme of Succession is legendary
