spotify doesn't care about mission control settings I have my Mission Control (el capitan, 10.11) settings the way I like:
"When switching to an application, switch to a Space with open windows for the application" is OFF.

This works very well except for Spotify. Also, I have Spotify "locked" for a specific Desktop.

It's very annoying to do a cmd-tab and switch 3 desktops. And then, it doesn't switch back with another cmd-tab.

How can I make Spotify obey the Mission Control setting?
Spotify doesn't support multiple windows. The reason for this statement is absence of New Window in File Menu. So it switches to the desktop it is at.
