What technologies to use?

Question

Python

Hello! For educational purposes, I want to develop a small analogue of Spotify, in the sense that I will make a web server that will store music and an application for desktop and Android with the implementation of the Spotify Connect functionality, i.e. so that using the application on one of the devices you can control the playback of music on the other. What technologies are best suited for solving such a problem? To implement the server side, I look towards node.js using sockets to synchronize the application that controls playback and the application that plays music. To implement the desktop version, I would like to use python, but are there any libraries that allow you to play music from a remote server? I would also like to know in which direction to dig, in order to to implement an application with such functionality for android. Thank you!
