I'm an Amazon Prime customer so I have access to their Prime Music service, though it's not the unlimited version; which I understand to mean that a subset of the music in Amazon's catalog is included for streaming but not everything. My question is ... when I enable Alexa on the Sonos One, by default, the device is authorized by my Amazon account. Does that mean when I tell it, for example, "Alexa, play Jimi Hendrix", the only songs it will select are those which are free per my Prime account? In other words, can I be confident that Alexa won't select an artist's songs not included in my account and charge me for playing them?
My intent with enabling Alexa was to use it to play music from my personal library on my NAS, but learned on this community that this isn't an option (and I concur with the vast majority of comments that this a huge gap in the product's functionality). So if I'm going to bother using Alexa to play music, I don't want to find that Amazon has billed me for a lot of songs that it chose to play.
