Spotify launched their ‘Spotify Connect’ service a little over a year ago, which allows all your Spotify connected devices to play nice. Whether on a mobile device, desktop or wirelessly streaming to a speaker, everything talks to each other.
Spotify recently included a feature ‘Spotify Remote’. The remote app will allow you to wirelessly control your Spotify library on your desktop or laptop, from your phone or tablet.
Spotify Connect is still exclusive to Premium user and with this new update it could be worth the upgrade.
