mp3menu
An audio player for the Linux console.
... (Press CTRL-ALT-F1 to get to the console), but there's no reason it shouldn't work in a terminal emulator (xterm, etc).
Move, copy or symlink the script to somewhere on your $PATH. Type mp3menu on the command line.
If the system variable MUSICDIR exists, mp3menu will cd to it before starting up. You can set this by adding
export MUSICDIR=~/music
to your .profile or other startup file. If the variable is not found, mp3menu will start up in the current directory.
