+I'm a **BIG** fan of **[Spotify](https://www.spotify.com/)**. I use it every day, hours on end. 
+I like the fat client though, I find the web version way too buggy and unstable.
+
+At ING, we use a HTTP proxy and I have configured Spotify to go through the proxy. At home, I don't use anything. 
+This means that every day, I have to go back to my settings, disable / enable the proxy and restart Spotify. This is very annoying.
+
+So annoying in fact that I started using the web player at home, to my disappointment.
+
+Finally, it go me tired enough so I decided to dig deeper into the issue and find a solution. **It had to be possible to automate this.** 
+
+
+The first step was to find the location of the config file. On my Macbook, it is located in __$HOME/Library/Application Support/Spotify/prefs__.
+In this file,  I saw the line : __network.proxy.mode=1__.
+The rest is child's play
+
+Here is the final script I came out with to enable/disable spotify's proxy settings. I called it **spotiProxy**
+
+```bash
+#!/bin/sh
+
+ON_OFF=$1
+SPOTIFY_PREFS="$HOME/Library/Application Support/Spotify/prefs"
+PROXY_ON="network.proxy.mode=2" #HTTP Proxy
+PROXY_OFF="network.proxy.mode=1" #No proxy
+
+if [ ! -f "$SPOTIFY_PREFS" ]; then
+    echo "Spotify preference file not found. Exiting"
+    exit 1
+fi
+
+if [ "$ON_OFF" = "on" ]
+then
+    echo "Activating Spotify proxy settings"
+    sed -i -e "s/$PROXY_OFF/$PROXY_ON/g" "$SPOTIFY_PREFS"
+elif [ "$ON_OFF" = "off" ]
+then
+    echo "Deactivating Spotify proxy settings"
+    sed -i -e "s/$PROXY_ON/$PROXY_OFF/g" "$SPOTIFY_PREFS"
+elif [ "$ON_OFF" = "show" ]
+then
+    cat "$SPOTIFY_PREFS"
+    exit 1
+else
+    echo "Invalid command entered. Please use 'spotiProxy on' or 'spotiProxy off'"
+    exit 1
+fi
+
+number_processes=$(pgrep Spotify | wc -l)
+if [ $number_processes -gt 1 ] 
+then
+    echo "Restarting Spotify"
+    osascript -e 'quit app "Spotify"'
+    sleep 1
+    open -a Spotify
+fi
+```
+
+It's usage is very simple :
+* Call it with `spotiProxy on` (or off)
+* It will set you settings accordingly, and restart Spotify if it was already running.
+* Enjoy!
+
+This script is run automatically every time I arrive at home or at the office. Nothing to do any more. Joy!
