Metadata

Yes. Major streaming platforms like Apple Music and Spotify strictly require the real first and last legal names of the songwriters for copyright and publishing purposes. You cannot use your artist name or DJ moniker in the composer or lyricist fields.

In music distribution metadata, the "Composer" is the person who created the melody, harmony, or the instrumental beat. The "Lyricist" is the person who wrote the actual words of the song. If you wrote both the music and the lyrics, you must assign yourself both roles to ensure royalties are routed correctly.
