"CMus is very powerful and highly configurable, and it
features Vi-like commands and keyboard shortcuts which can be bound
to other keys if needed. It supports various audio formats,
including Ogg Vorbis, FLAC, MP3 (with libmad), WAV, AAC or WMA.
CMus is lightweight and I must say that it was a delight testing
it, and although by default it lacks support for one of the
features I consider a must-have, the Last.fm song submission, this
can be accomplished by applying a patch and recompiling it.
"The first thing you will want to do when starting CMus is to
add some music folders. You can do this by typing :add
/path/to/music/folder/, then navigating through the playlist by
using the J and K keys or using the Up/Down arrow keys. To start
playing press Enter and to stop CMus use V."
