Forced to use spotify connect

[Exorchist]

No matter if I login with Facebook or "other login", I always get routed through my smartphone app. I even tried turning off my phone when logging on, but as soon as I start my phone back up, the spotify app there says it's playing through the PS4. Highly annoying! What's even the point with the "other login" feature if it works exactly like the facebook login?

My amp has spotify connect already, why would I want the PS4 to use the same system (and with worse sound at that)? I want it to work like it does on my PC, just a normal streaming service with pretty UI.
