Interestingly if I boot cleanly and start spotify from the dash I end up with a grey icon.
If I then close the spotify window (but spotify is still running - seen in the indicator area) the icon disappears from the launcher (as expected)
I then start spotify from the dash again (which raises the spotify window) I now get a spotify icon in the launcher.
