App researcher Jane Manchun Wong shared her discovery via Twitter late last month. In the demonstration, lyrics popped up alongside a YouTube video of Rick Astley’s “Never Gonna Give You Up”.

— Jane Manchun Wong (@wongmjane) April 19, 2019 The timing of the lyrics looks pretty accurate as far as we can tell. The tweet itself has no sound, but you can always have the video playing on another browser, and decide for yourself. Despite being discovered last month, Instagram hasn’t made any announcement regarding the feature just yet. Of course, it’s also entirely possible that it will never make it out of the testing phase. Only time can tell. (Source: Jane Manchun Wong / Twitter via The Verge)
