Is there no such thing as profiles?

[Keeper]

In Netflix I would never see what my girlfriend is watching on Netflix, if she logs into her own profile.

I've made profiles for subsonic, but even if we log into our seperate accounts, we keep seeing what the other person is playing. (Using "MusicStash" App)

I've unticked "Let others see what I am playing" in the personal settings inside the Subsonic server settings (for each profile). I have also unticked "Show what others are playing".
Still nothing.

Is there no such thing as seperate profiles? I don't want to see her ABBA stuff every time I open my profile.

Apps are, so far, using the subsonic api, have a look here .... http://www.subsonic.org/pages/api.jsp subsonic is not responsible what the app is doing and what api calls are used for a result.
In my opinion, using the subsonic web interface it should use your settings.
