Spotify in notification

Hello,
 I have made a little script that sends a notification of the Artist, Album and Song that is playing on Spotify.
It is checked every fifth second but not updated if it has not changed.
Change the sleep command to change the update frequency.

So I thought I would share it with the world :)

#
#    Purpose: Pop up notification of what Spotify is playing.
#    Usage: Start Spotify then start this script. This script will self exit when spotify exits. 
#    Dependencies: libnotify-bin, sudo apt-get install libnotify-bin to install it.
#    Troubleshooting: Test this command notify-send "Artist" "Album" in a terminal.
#
#    This script is distributed in the hope that it will be useful,
#    but WITHOUT ANY WARRANTY.
