I've spent a few weeks using a beta of the new Sonos app which is to be released this spring. Sonos was one of the first companies to embrace the Mac when the company launched its whole-house wireless music solution back in 2002. When Apple allowed apps in iOS, Sonos was front and center with an app to control the system.
The original 'blue' app has been around ever since, but the new app, reworked from the ground up has a nice fresh design and some important feature upgrades.
The most significant new feature is universal search. For example, type in the name of an artist and you'll find relevant tracks in your music library as well as across any streaming services you subscribe to. You might get pointed to Pandora, Spotify or something else.
The app itself has been simplified, and there are now three main areas; What's currently playing, what room it is playing in, and how to navigate to the next song you want to hear.
