The social network "Facebook" is continuously working on adding new features to its list of updates. Users are getting into facebook in such a way that they are sharing frequent updates about 'what they are doing' with their friends no matter if they are feelings or activities.
Facebook stated in a Blog Post : At the time of posting a status update on Facebook, Users' have the option to use your microphone to detect what song you are listening to and what movie you are watching on your television set (if this feature is turned on).
Idea Behind Its Working:-
Here’s how it works: If you’ve turned the feature on, you’ll see an audio icon moving on the screen when you write a status update. If the feature finds a match, you can then choose to add the song, TV show or movie to your post. If you share the music then your friends will be able to listen a 30 Second preview of the song you are listening to.
The above screenshot is showing how it looks when this feature is turned on or off. Facebook is currently working on this feature and will soon introduce it to real world.
