How to make a broadcast with music 24/7?

Question

YouTube

Sobsno there are channels on YouTube that broadcast music around the clock (still signed in red in a red frame - "NOW LIVE"). instead of a video, usually an animated picture or just a picture with a logo.
Interestingly, in some broadcasts, along with the tracks, the name of the track changes in the picture.
So, I just started to figure out how to compose questions for Google correctly in these matters - I don’t understand yet.
Hoping for advice from those in the know. Please explain how this system works, how it works and what software is needed, if needed.
