Stores require that you enter your actual artist name in the artist name field, when uploading. Do not list your artist name as "Cool Guy Records" and your song title as "Song Title (feat. Actual Artist Name). Stores will reject this.
Also not accepted as an artist name: Dave COOL GUY (or something similar... You get it) - When you reference your label name in your artist name.
If you need additional slots so you can have multiple artist names, and specify your label name, please consider upgrading: https://distrokid.com/plan/
