If you've been pining for a new way to show off your singing chops, you're in luck. Facebook is apparently developing a new show that will have users record their performances and send them in as an audition. According to researcher Jane Manchun Wong, who found the feature in the Facebook app's code, there's a new interface to find popular songs and then record your own rendition of the tune. Wong says that the feature "feels like a cross between Musical.ly and Fifteen Million Merits from Black Mirror."
