Spotify always opens on primary screen

I have Spotify premium, using the desktop application. On my computer I have two monitors, the second is dedicated for additional programms, such as my music player. When I logon my Computer, the app always starts on my main window, blocking all my view. This occures, when I start "cold", restart and after hibernating.

Start spotify manually

The solution was fairly simple but tricky to find with experimenting.

At first I found out, that spotify has a option "Start Spotify on Login". I deactivated it and restarted Spotify manually. And suprisingly: Spotify started on the second screen as wished.

But the function that Spotify starts on Login is convenient. So I put a shortcut of Spotify.exe manually in the windows autostart folder:
C:\Users\[User]\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup
