The Sonos app isn't going anywhere, so if you prefer it you can just continue as normal. Teaming up with Spotify, however, is a smart way for the company to make its speakers more flexible. Sonos is fighting on two fronts; in the hardware game, it's up against a deluge of high-end speakers, as well as the Assistant-powered Google Home and Alexa-integrated Amazon Echo. On the software side, it's tackling Google Cast and the oft-forgotten AirPlay. To keep its speakers attractive, Sonos needs to work with dominant and emerging services -- if it doesn't, the company's hardware will soon feel uncooperative, rather than seamless in the home.
