Make sure your Spotify desktop app is up to date Now you can cast your music to Chromecast from the desktop app without having to use the iOS or Android app. You can now find Chromecast in the connect “devices available” menu in the Spotify desktop app and browser web player. In this version, you can simply use the usual “devices available” menu to see available Chromecast devices. The news comes via Spotify Rock Star MattSuda - as they note, you’ll find the feature in desktop app version 1.1.38. You’ve long been able to control Chromecast streams that were initiated from the iOS and Android apps (via Spotify Connect), but now you can initiate those streams directly from your Windows or Mac desktop. After many, many years, you can now initiate a Chromecast stream from the Spotify app for desktop.
