Facebook Shazams Itself | Re/code

A new automatic oversharing option

"The company said it will soon introduce a mobile feature that can identify the music you’re listening to or TV show you’re watching while you’re posting on Facebook from your smartphone.

When you turn the option on, your smartphone will detect the sound in your environment while you’re tapping away a message or uploading pictures or videos from your iOS or Android device. So if you’re cranking Slayer’s “Reign in Blood” on your speaker system, Facebook will recognize that, and you’ll be able to include as much in your status update."
