I initially didn't understand the necessity of Sonos. I can play music on my phone to any Bluetooth device. However, Sonos has created a variety of hardware solutions that lets you stream anything seamlessly and effortlessly (VIP adverbs). They produce a device that works with your sound system, as well as a soundbar for your television (the Playbase is their latest release), or a standalone speaker. These devices allow the user complete control of the music by being service provider agnostic; you can choose Apple Music, Amazon Prime, Spotify, Audible, or anything you prefer. The user interface is great and a fantastic solution for your outdoor BBQ. And remember, don't let anyone get your wifi and hijack your system for the night!
