How to implement streaming music on the site?

Question

Audio broadcast

I want to make an online radio like this https://listen.moe
Since I have little experience, the question of how to implement such music broadcasting puzzled me. I reviewed a few answers, for example with nginx rtmp, but my knowledge does not allow me to figure it out. I also looked at something using js libraries, but I'm not sure about this either. The question itself is, what is the easiest way to implement this?
For your information, my backend is on django
