well i think its slipping down because most people wont use the boxee as a musicplayer.
i use my boxee box for videos (and sometimes surfing/apps)
when listening to music/spotify i use the squeezebox.
so im glad that they arent prioritizing spotify and instead use the time they have on better things like bugs and features that are for video and not audio
