Since its Australian launch back in May, Spotify has made big waves in the local streaming music market, thanks in no small part to its association (and leverage) with Facebook. To even sign up with Spotify in the first place you’re obliged to provide your Facebook login, and the default settings mean anything you listen to could be posted to your Facebook friends, either within Spotify or via their Facebook newsfeeds. While the existence and scope of this feature clearly elevates the 'socialness' of Spotify (and is a pretty killer tool for music discovery to boot, as it lets you in on all sorts of artists your friends are listening to which you might otherwise never have stumbled upon), it’s also a bit of a double-edged sword, automatically publicising musical sojourns you might otherwise wish to keep private.
Luckily, it’s easy to turn the auto-sharing off, keeping your forays into dubious genres strictly between you and Spotify. From within Spotify, if you go to File > Private Session (Spotify > Private Session on a Mac) you can temporarily prevent the app from broadcasting your actions. But if you really want to opt out, go to Edit > Preferences (Spotify > Preferences on a Mac) and untick all the sharing options in order to permanently go incognito, ensuring Spotify’s sweet nothings are reserved for your ears only.
