first of all, great work. I really like rune audio.
But i think there is a little bug. When you enter an incorrect password for spotify and try to connect, it will run in an infinite "connecting" and won't time out.
+1 for this. I'm currently looking at a "connecting" message that will not timeout. I deliberately changed my spotify username in settings to an incorrect one in the hope that I could re-select the output to be via MPD instead of Spotify. It wasn't to be. I have rebooted my Pi from the command line. The same behavior persists. Looks like a fresh install for me! System is RPi model 1, Rune 0.3-beta
