Bluetooth speaker for Spotify and headphones for everything else

[JohnCarver]

Hi folks,

I want to play my music the way I did with both Apple Music and Qobuz: I use my bluethooth speaker to play my music and I use my headphones to play every other sound my system makes. I want ambient music in the room and computer sounds in my headphones only. 

How do you do this in Spotify? I have the Mac desktop app.

If I understand your question properly, this isn't available natively but you could try using an app such as https://rogueamoeba.com/loopback/ to do this.
