I have successfully setup Chrome and iTunes however I am having a constant issue with spotify. This is how it's laid out right now, forgive me if it looks a mess, I experimented a lot and Spotify is the issue here.

Spotify does not close upon pressing the Red X. You can only close it via File/Exit or right clicking the bottom right taskbar icon and pressing quit.
You say Task Kill? Well, yes, that's exactly what I am trying to perform, however what I can't find, is the event to trigger it.
When X or Minimise is pressed, the event 'Task.Deactivated.Spotify' is all I have to run on. There is also 'Task.Activated.Desktop".
I experimented with both for a brief time, yet found out that they were both used too much and caused XBMC to boot up prematurely or in inappropriate instances.
You'll note that in the screenshot I have created a CMD file that terminates the process when run. So the only part I can't get to happen, is to connect that CMD file, with the Spotify Red X.
What I want to do?
Well Spotify starts up perfectly, maximises automatically and everything. I am configuring this system to work with technophobes, so preferably I should press the X and XBMC will boot up.
What I can't do?
Press the X and terminate spotify.
Final note:
I've seen threads around here, I've browsed and searched for a solution, yet I couldn't find one. I'm not educated with scripts, which is why I'm trying to solely use the plugins. If you do advise me on scripts, please bare with me. At the time of that screenshot I was reconfiguring the iTunes setup, so ignore any instances there, Spotify is the issue.
