What shows had particularly good song selections, that introduced you to artists you might otherwise have never discovered?

Scrubs immediately comes to mind, though it's not a very current reference. I still listen to Colin Hay thanks to these scenes. And this one.

The music choices were almost always spot on, exactly matching the tone of the scene
- I was sad when I learned the episodes now available on streaming don't have the same music - apparently the rights expired and they had to change many/all of the songs. I only checked one episode and immediately went back to my low-res, offline copy
Had to double check myself but that's the guy from men at work.

Silicon Valley. The songs they played at the end of every episode were pretty much universally bangers.

Not a show, but Tales From the Borderlands introduced me to Jungle, possibly my favourite music artist right now, as well as a few other gems.

Jungle fuckin rocks
The episode intro with "To The Top" by Twin Shadow is amazing.

Breaking Bad & Atlanta both had many new discoveries for me. Twin peaks s3 had some amazing music but I was aware of the majority of the artist beforehand

Edit: add Sharp Objects. Amazing sound design and found a few new gems

The Top Gun soundtrack definitely sets the standard.

If we're doing movies, Pretty in Pink was always my jam.
- Grosse Pointe Blank's soundtrack is absolutely amazing.

The Venture Brothers and J. G. Thirwell.

Cowboy Bebop and Yoko Kanno.

Definitely Bebop!

Sons of anarchy

Katey Sagal's cover of Bird on a Wire is one of most extraordinary things ever recorded. Tears every time.
Songs of Anarchy is pretty brilliant all around.
Sons of anarchy had some really good cover versions of songs (or a specific song I don't remember)
It was very good but rubbed me the wrong way for some weird random reason

The Americans. Whoever did the soundtrack for that show was amazing. Really great 80s music.

Agreed on The Americana
Justified introduced me to modern gangsta crossover folk music

Smallville always had well curated songs for each episode.. at the time some were fairly obscure bands

Remy Zero!

The Bear has an awesome soundtrack

Definitely Arcane for a start. I'll probably think of others later.

Peacemaker! So many good songs from bands I've never heard of. Especially Wig Wam and Band-Maid.

Dark

Everything from Jody Hill / Danny McBride: Eastbound & Down, Vice Principals, Righteous Gemstones all have amazing soundtracks.

Righteous Gemstones has some great music. Not really into country or gospel either, but they found a few winners that work for me.

Rick and Morty

Stargate Universe

So many good recs on here. True Detective S1 really nailed it for me though.

Breaking Bad and Stargate Universe both come to mind. Also, a couple from House M.D.

Dark on Netflix

Letterkenny introduced me to Japanther, Black Mountain, DZ Deathrays, and a bunch of other bands that would never hit my recommendations on any streaming services.

CSI Miami had a Papa Roach song I liked a lot better than that cheap knockoff of the original CSI.

As a person with an interest in the history of movies I got throw in The Big Chill. It was the OG film soundtrack, I’m pretty sure it was the first soundtrack to hit the billboard top 10 albums in a time when that meant something and is full of ‘50s & ‘60s bangers.

Final Space. They had a fairly unknown artist make masterpieces for them.

The outros in Hit Monkey introduced me to a lot of new artists. Here's a playlist of some of them: Hit Monkey

Mr. Robot

The show was kinda lame, but Shrill had a pretty rocking soundtrack

The soundtrack for euphoria was amazing- in context anyway, been meaning to look some of it up.

Killing Eve. I got into so many artists only from the soundtrack.

Supernatural and Kansas

Monkey Dust, and in a similar but less animated vein Blue Jam both had great music picks joining sketches together.

True Blood

Kipo and the Age of Wonderbeasts

I loved cliff martinez's ost for "the knick" breaking historical accuracy that obviously did the show really well.

Lucifer
