Nonsense.  Whatever the problem is, the reason will be commercial (money) and nothing to do with presumed cultural or political censorship. 

Fair enough. I misspoke. It’s not censorship, but there is definitely some licensing or other issues with certain songs and not being able to play them in the Sonos app. Just trying to get an understanding as to why this occurs (more often recently). 

Why are you complaining about Apple Music licensing issues on Sonos’ support site?  That’s like complaining about the TV writer’s strike to Samsung’s TV support.
