Instagram now allows you to add song lyrics to your stories:
To play with the feature, first select the Music lens type (amidst Boomerang and other options) before you shoot or the Music sticker after. Once you pick a song, you’ll see lyrics pop up which can help you cue the segment of the music you want to play. Then you can cycle through a bunch of animation styles like traditional karaoke teleprompter, a typewriter version that preserves mystery by only revealing lyrics as they’re sung, and big flashy billboard font.
