Plain Lyrics are just the plain text of your lyrics. Plain Lyrics are available in Apple, Google, and Lyricfind.
Synced lyrics are lyrics that are timed to your music. On platforms that support synced lyrics, like Apple Music, your fans will see your lyrics scroll in time with your song for the best sing along experience.
Note: Synced Lyrics are only available on Musician Plus and Ultimate subscriptions. To get synced lyrics on Spotify and Instagram, create a free Musixmatch account to submit your lyrics here.
