Git commit hook to show what you're listening to.

#!/usr/bin/env ruby
#
# Place this in your $PROJECT/.git/hooks directory
# File should be named 'commit-msg'
# Ensure you have dbus bindings for ruby installed
#
#
# Limitations: 
#  * Only works for Amarok so far, as that's what I use.
#  * If your songs are tagged poorly, your commit message will be also.
