Music platforms show only some song credits, not all.
Besides the Main Artist, most platforms show:
Composer and songwriter.
Featuring artist.
Producer.
For these people to appear in the credits of your songs, you must upload their names exactly as they appear on the platform and roles in the "Artist" field on each track on the limbo music platform.
Important
Please write the artist names precisely as they appear on the music platforms.
For example: if you add a Featuring Artist like "Andrés López" but his Spotify Artist Profile is "Andres Lopez" (without accents), Spotify will index the song in the incorrect profile "Andrés López."
