As you've probably seen on Instagram, you can now display lyrics to audio clips in the stories. Facebook & Instagram have partnered with the Musixmatch service to add lyrics to each song.
How does it work?
Ideally, you don't have to do anything, because Musixmatch has already entered your lyrics automatically. Especially at the beginning there can be delays. In this case simply register at Musixmatch and verify your artist. Then you can add, change and synchronize lyrics.
