The Instagram application not only offers the possibility of uploading music to stories, but also allows you to share the lyrics of the songs.
If you want your lyrics to be available, you must make sure that they are correctly entered in MusixMatch.
You can add them yourself for free to make sure they play correctly. We also recommend that you verify yourself as a Verified Artist and use the New Release form for future releases.
If you cannot find your releases on Musixmatch, you will have to contact them, through this link in their Support Center: https://support.musixmatch.com/article/137-musixmatch-is-missing-a-song-could -i-add-it.
