I've been listening to podcasts of Mindwebs, a grand 1970s radio show which read science fiction and horror short stories. The readings are excellent. There's music, often electronika. Some stories have multiple voice actors. A ton of them are hosted on Archive.org.
Stories range across the 20th century, with somewhat of a focus on the 1960s and 70s.
The stories tend to be gloomy, curiously. They often end badly, or sarcastically. Even the older stories are grim in the end.
