From the webpage:

MOC (music on console) is a console audio player for LINUX/UNIX designed
to be powerful and easy to use. You just need to select a file from some
directory using the menu similar to Midnight Commander, and MOC will
start playing all files in this directory beginning from the chosen
file. There is no need to create play lists like in other players. If
you want to combine some files from one or few directories on one play
list, you can do this. The play list will be remembered between runs or
you can save it as an m3u file to load it whenever you want. Need the
console where MOC is running for more important things? Need to close
the X terminal emulator? You don't have to stop playing - just press q
and the interface will be detached leaving the server running. You can
attach it later, or you can attach one interface in the console, and
another in the X terminal emulator, no need to switch just to play
another file. MOC plays smoothly, regardless of system or I/O load
because it uses the output buffer in a separate thread. It doesn't cause
gaps between files, because the next file to be played is precached
while playing the current file. Internet stream (Icecast, Shoutcast) are
supported. Key mapping can be fully customized. Supported file formats
are: mp3, Ogg Vorbis, FLAC, Musepack, Speex, WAVE, AIFF, AU (and other
less popular formats supported by libsndfile. New formats support is
under development. Other features:

* Simple mixer.
* Color themes.
* Searching the menu (the play list or a directory) like M-s in Midnight Commander.
* The way MOC creates titles from tags is configurable.
* Optional character set conversion for file tags using iconv().
* OSS, JACK, and ALSA output.
