Spotify's apps now support Google's Chromecast Audio
Andrew Tarantola for Engadget:
If you have a good set of speakers and want to stream music to them, the Chromecast Audio is a simple and inexpensive way to make them work with almost all of the the top music services. The combination of a great price point, wide compatibility and dead-simple setup makes it easy to recommend.
This favorable review from Engaget, in combination with Spotify's announcement today of building support for the streaming dongle into their app for iOS and Android, makes me hopeful for a quality replacement for my aging, and super unreliable, Airport Express.
