I have a Samsung Galaxy 4 running the latest OTA.. Does anyone have any suggestions as to how I might be able to start a music streaming app such as Pandora or Rdio on a specific channel in the morning, and shut off in the evening? I see plenty of "sleep" timers for these apps, and i think a few have an "alarm" function. Is there already something geared towards this usage, or would i need to do something like Alarm Clock triggers Automate app triggers Sleep Timer? Any assistance would be greatly appreciated.. Thanks
