I started listening to music on the radio. Now I run my own radio for personal use.
It’s run on MPD and it broadcasts at 320kbps over HTTP. Internet radio is now known as streaming, like Spotify and Pandora.
MPD is a server daemon which loads your music folder into a database. It allows playing on outputs like the sound card, http, icecast, and probably more.
Clients then connect to the server and load the database over the network to display on Web, Mobile, Tablet, you name it!
