Thank You very much for your answer.
I am intrested in getting a complete solution for media and home automation and is looking into Dianemo.
Today i am running LMS with the spotify plugin from Triode and have added several entries of the spotify plugin with different spotify accounts (spotify family subscription). Ex: https://github.com/mika-fischer/triode-spotify-clone
As i only use spotify for music it is of great importance to be able to use multiple streams.
