Hey @csumb_biscuit, thanks for reaching out to the Community!
I'm glad to hear you would like Spatial Audio support on your AirPods Pro to work with Spotify, as I do too! I'm afraid this feature isn't possible at the moment, but I could see how this can be useful.
It'd be great for you to go add your +VOTE as well as subscribe to this related Idea. All the updates you need regarding this will be shared there!
I'll be here if you need anything else!
