Playback freezes at end of track.

Hi - I've just instlled Mezzmo on Windows PC and am driving it via Android app to cast to Chromecast speakers. All fine and dandy. Except: It seems that unless I am actively viewing the mezzmo screen playback freezes at the end of whichever track is playing and will not step on to next track. So, if I'm say, reading an email or if the screen shuts down after inactivity. The music stops at the end of the track. If I return to the Mezzmo page everything immediately starts again, next track begins, etc. But, only until the end of that track, unless I keep watching it. It can't be right that one has to spend the entire time looking at the Mezzmo screen in order to listen to music, can it???

Please check the power settings in Android to make sure that the app is set to run in the Background.
