It does have a flashing blue light to indicate it is on.

If you do go to the Pi3 let me know and I will send you a special link to get code to reflash your SD card.

Have you tried putting the Playlist on a USB drive and playing it from the AxiomAir UI? This works really well.

It is a "last button pushed" order of priority so if someone plays something over Bluetooth it will take over from what was playing on WiFi and vise versa. We do however recommend you stop playing one thing before going to the next because sometimes a timing error will occur if you don't, and you will get odd song title and volume things that require a song switch or volume touch to clear.
