DIY Streaming Radio 2024

Let's say I want to make website with a streaming audio. The audience can go to the page and listen in like they were listening to a radio station (every listener would hear the same audio at the same time). The back end would just be some sort of thing and a folder with a few hundred audio files and it's just randomly playing through them (ideally there would be a way to specific some station identification files to every three or four times and a way to not repeat the same files too often). Is there a way to do this that doesn't involve a third party service? What is the smartest easiest way to do this in 2024?

Thanks.
