Huh... so for the past couple weeks there was a top level "discover" tab on the iPhone app (so Home/Discover/Search/Your Library), and when you clicked it it would just a random song in a weird full-app video playback UI, with the only exposed controls being "go to this album" and "skip", no output device selector. I went back to check today to confirm that even if I had an existing network device selected it'd disconnect that and only play locally, but clicking on the tab just showed an error page. I force quit the app and relaunched, and now the tab is gone entirely. Guessing I was in some A/B experiment of a pre-release feature, it'll probably have more functionality in the full release (assuming they didn't can it)
