Pi Radio Streamer
Overview
Stream radio stations to a Chromecast via a Raspberry Pi
A spiritual successor to the old Now playing app, which was a read-only way to see what music is currently playing on a Chromecast Audio.
This is something similar that can run on a Raspberry Pi, and can then be displayed on an iPad (or similar).
It shows details of the current track that’s playing.
This app can also be used to start radio stations, such as BBC Radio 6 Music or FIP.
Full setup instructions are on GitHub.
