I’m looking for a little information on streaming in general. My wife would like an Alexa for Christmas. My understanding is you need a subscription to stream music for one of them. I was thinking this might be the nudge to get me into streaming. Are there any services out there that would not only work with Alexa but have high def. music files as well? I know absolutely nothing about streaming. If anyone knows of a site that does a good job explaining it that would probably be very useful to me.
