I entered DaveOS Music for you but as you are on a FREE plan, your label will be iMusician I DaveOS Music. Otherwise, you can also buy a premium label so that the branding is not appearing.

You can credit many producers, however contributors and performers must be entered with their legal names. Artist names are not accepted anymore for contributors and performers.
