I hate how Musiccast can only do spotiy connect and the user has two use to apps to search music and control volumes in zones. Apple music is the same...Airplay only. It's not even Airplay 2 compatible, which would make it easier to stream to multiple rooms from an iPhone.

I wish someone out there would design a system allowing Apple Music and Spotify (the two most popular music services) to be controlled within their app so I wouldnt have to tell old low tech, confused customers to have to use more than one app to control things. It would only take a couple of months to figure it out Im sure.
