Sonos aims to make it easier for you to navigate through its Controller application with 5.0 version of the app. Central to the app’s redesign is the search function. It lets users look for any artist, song, or album across the many services Sonos uses (such as Rdio, Spotify, Pandora, iTunes, etc.). The user interface is easier to navigate and it lets you control multiple rooms at once. You can choose to play different songs from various services or have everything playing the same thing. A discovery feature has also been added to help you find new tunes. The iOS update will reportedly come out in the spring.
