@mahler123 The Node does stream Amazon over the network. It has a limited function app built in for Amazon. If I remember correctly, you needed to use the android or ios app on a phone to create or manage lists and favorites, as the Node UI did not do that...it just played your albums, playlists, etc.
I found that Tidal connect was integrated better.... not wanting to use separate devices to manage or play my music.
Although Tidal and Spotify both offer the "Connect" api, for the best integration on Node, I ended up with Qobuz for the superior SQ.
