MPD (music player daemon) is an audio player that has a server-client architecture. It plays audio files, organizes playlists and maintains a music database, all while using very few resources. In order to interface with it, a separate client is needed. Backlinks ncmpcpp
Ncmpcpp is an mpd client (compatible with mopidy) with a UI very similar to ncmpc, but it provides new useful features such as support for regular expressions for library searches, extended song format, items filtering, the ability to sort playlists, and a local filesystem browser. To use it, a functional mpd must be present on the system since ncmpcpp/mpd work together in a client/server relationship.
