Cmus
cmus is a terminal-based audio player that runs entirely within a terminal window, using the ncurses library to render its interface without any graphical toolkit. It is designed to play local music files and internet radio streams, with support for CUE sheet metadata that splits single audio files into logical tracks with correct timing, and gapless playback that eliminates audible pauses between consecutive tracks.
The player distinguishes itself through a Vi-inspired incremental search interface that locates tracks and commands in real time as you type, and a tab-based workspace model that organizes the interface into independent views for the library, playlist, and file browser. It also provides a Unix socket IPC interface for remote control from external programs, and can execute external commands with selected tracks as arguments. Volume normalization is handled through ReplayGain metadata, adjusting playback levels per track or album for consistent listening.
Additional capabilities include a play queue for arranging upcoming tracks, playback state persistence that remembers and restores the last position on restart, and scrobbling support for reporting played tracks to Last.fm or Libre.fm. The interface supports keyboard shortcut customization, tab-completion command execution, and dynamic playlist filtering that refines the visible track list in real time.
