Spotify is pretty great. But, if you're like me, you probably prefer to stream your music to somewhere other than your computer - such as a stereo, or a whole home intercom. Spotify has built-in AirPlay compatibility - IF you have a premium subscription. I don't. I DO, however, stream every other kind of music from my iMac or iPad using AirPlay - Sirius XM works great in that regard, and obviously iTunes was built for it. But not Spotify.... Until I learned this simple trick. Hold down the Mac option key, and click the volume control icon at the top of your Mac's screen. Now, you can see a list of output devices, and can see your AirPlay speakers. Click on one of them. Then just fire up Spotify, and AirPlay your music wherever you choose! NOTE: You'll be streaming EVERY sound that your Mac makes, so close the rest of your programs - if your kid has some Nick Jr. Flash game running in Safari, you'll hear that alongside your music, too.
