Infinite Fun – mpd-client.sh

A simple mpc (Music Player Daemon's client) wrapper + libnotify to control your music via command line or keyboard shortcuts

In Linux I use echinus or OpenBox, with a lot of custom keyboard shortcuts. Being able to control the volume is something I think should be really easy, with no need to use the mouse, the mouse scroll or even open a whole application just to mute it. The same for playing/pausing/stopping music, so, I write this kind of scripts in order to be able to link some actions to keyboard combinations.
