Hi,
This is something of a confusing concept, and we have not done the best job explaining it, so it's understandable that you're confused! The music shown under Music Library on the WebUI will only display music from either a USB drive plugged into the AxiomAir, or from a NAS drive that you have configured. Music that resides on your phone or tablet will not be displayed here, as the typical use case is for you to select and play the music on your device and send it to the AxiomAir via AirPlay or uPnP. Once you have connected to the AA hot-spot WiFi network on your iPhone, simply swipe up from the bottom of the screen and tap AirPlay. One of the options displayed will be AxiomAir. Tap on it, click done, and then any music you play on your iPhone will play over the AxiomAir.
Thanks,
Andrew
