I just signed up for premium and the first thing I seem to have found is the single-stream limit. Ok, so I need a family plan... but then to use that on my Alexa devices I'll have to make a separate Amazon accounts for each device to associate with the separate Spotify accounts. So it seems like it's not possible (or at least not plausible) to have multiple Spotify streams on my Alexa devices.
Is that true? Or maybe family account streams are pooled and you can have multiple streams from one account then but with a total stream limit?
