OK I tried this several times yesterday once I noticed it, with repeat on and off, using playlists, albums, composers, and artist lists. I tried Shuffle on and off as well, and could duplicate it in all cases. This morning it works as you describe, as long as the repeat queue is on. Not sure what would cause this to fail, as I didn’t reboot the device, or even kill GMMP. So looks like I’m the bad guy here for whatever reason. Sorry for the false alarm.
