I guess anyone who has used Spotify knows that if you click the red 'X', it doesn't close, but just minimize.
From reading various websites, it is not a bug, but a deliberate ploy to have users keep it running becuase it is a P2P application.
Some websites suggest that uses should close Spotify by using the "File" menu on top and select "Exit".
But even doing that leaves SpotifyWebHelper.exe running, so you need to go into Task Manager and exit it there.
Is there a quicker, one step way to exit Spotify completely?
