Songwriters, producers, and remixers are credited/added individually on each track.
The full names (first and last name) of each lyricist and composer are required for every track you upload. Artist names or aliases are not accepted for these roles. (Only the Producer and Remixer can be an artist/alias or a band name.)
In the example below, the whole band (The Testers) composed the music/melody together, and Juan and Lisa wrote the lyrics.
Other contributors and roles are added under "Add Contributor". It's important that you only enter one name in each box and don't include any other information - for example which instrument the person is playing on the recording or which studio or company they belong to.
Composer = for writing the music/melody
Lyricist = for writing the lyrics
Performer = for individual band members or studio musicians performing on the recording
Producer = for producing the recording
Engineer = for other types of sound/recording engineering (e.g. mastering)
Mixer = for mixing the recording (e.g. mixing engineer)
Remixer = should be used if the track is a remix, and there's an original version available. Put the remixing artist's artist name both here and in the "Track version"
