Childish Gamino's song “Algorhythm” has been teased for months. It first appeared in an email to concertgoers who purchased tickets to the "This Is America" tour, and was performed at the shows. It hasn't made its way to streaming services yet, but you can hear the song on Gambino's Pharos AR app, according to a Billboard report.
Android phone owners can download the app on Google Play. But it's not as easy as pressing play: Pharos AR generates 3D images projected onto video from the camera, and users unlock the full song by directing the device to different areas. The app also comes with a multiplayer option.
