I've never heard of Tidal, do they have family plans like Spotify and Google? Tidal's web page doesn't seem to give pricing just a free trial. For me the family plan value at Spotify is a great deal, six accounts for $15 Cndn. per month. The wife and the four kids all get their own account on my tab. Do any receivers or equipment have Tidal software built in?
