Music Player Daemon (MPD) is a lightweight, flexible, server-side application designed to manage and stream your audio collection. Unlike traditional media players that bundle the user interface and audio playback into one heavy application, MPD runs silently in the background as a daemon. Core Architecture: Server and Client Split
MPD splits the music player experience into two distinct responsibilities:
The Server (mpd): Manages your local or networked music database, handles the audio decoding, controls playlists, and manages output hardware. It runs entirely in memory once started, utilizing minimal CPU and RAM.
The Clients: External applications that connect to the server via a lightweight network protocol over a network port (typically 6600) to send commands like play, pause, or search.
Because of this split, you can host your music library on a low-power, headless machine (like a Raspberry Pi or an old laptop) tucked away in a closet, while controlling playback from your phone, laptop, or desktop terminal. Key Streaming Capabilities
