Great news everyone, there are some big improvements coming to Amazon Music on Sonos. Amazon is now offering a new tier of account service too which you can read about here
. The new tier, Unlimited, is available on Sonos and includes their Unlimited Playlists, Stations and access to their full library of tens of millions million songs.
Now with the Prime Music or Unlimited Music accounts you'll be able to search your Library (purchased and uploaded tracks) and the Amazon Catalog (all their music). You’ll now see all their artists, albums and songs available through Sonos search.
