I had Amzn Prime fall off on me repeatedly the other night and it brought to light that it isn't reliable enough to be a stand alone method of listening. By the time I got thru messing with it and having it keep coming in and out, I was no longer in the mood to listen. I have had this happen with amzon music before and is not so reliable in the car, either. Pandora is more reliable but it too can have it's moments. Between their server outages, and being that it is dependent on internet, which also shuts down for maintenance, weather etc. periodically, it's noticeably (and often frustratingly) hit and miss.
Was happening with Alexa all too frequently and actually caused me to kick the echo dot to the curb completely.
Convenience can be addicting to the point that when it fails, it is more frustrating, perhaps. If Wifi is having issues, I have to disable it in my phone to get streaming to work sometimes. I don't think this sporadic reliability can ever really be fixed being the multiple systems that all need to be right for it to work.
