Nope.
Libraries require that you enter your actual artist name in the artist name field, when uploading. Do not list your artist name as "COOL BEATS PRODUCTIONS" and your song title as "Song Title (feat. Actual Artist Name)". Libraries will reject this.
Also not accepted as an artist name: Mark COOL BEATS PRODUCTIONS (or something similar...You get it) - When you reference your business / label / production house / whatever name in your artist name.
As a note, That Pitch does not work with labels, publishers, or any kind of entity that represents artists underneath. We strictly work directly with individual producers & artists.
If you need additional artist names, considering adding more artist profiles. You still must own 100% of the music. If you do not own the music, consider inviting your friend to sign up for That Pitch.
