Engineer Jane Manchun Wong, who has a track record of uncovering upcoming features by reverse-engineering code, spotted the in-development feature, which she described as resembling "a cross between Musically and Fifteen Million Merits from Black Mirror".
It seems that specific pages would be eligible for the feature, much like its trivia game show feature, and the copyright for the music is sourced through Facebook and Instagram's existing Rights Manager.
Whether Facebook intends it to be as dark as "Fifteen Million Merits" is another matter. In the "Black Mirror" episode, the characters participate in a dystopian talent show to escape the drudgery of their everyday lives, where they endlessly cycle on stationary bikes to earn "merits."
Facebook declined to comment on whether this feature will be rolled out when contacted by Business Insider.
