A. More Sonos overlap of music playing, ability to like, heart, thumbs up, etc.
B. Likes, playlists and other show up from YouTube, spotify, audible, Amazon music, pandora, etc. In a current/main feed, last payed music, and visual previous search
C. Integrations from apps likes and playlists from other apps visible. Using better APIs with other companies apps.
