We strongly suggest sticking to 3-4 single details when requesting an additional verse. If more than 3-4 single details are supplied, your artist will use their best judgment on which ones to include. We always strive to weave in as many details as possible without making your song sound or feel clunky.
We set limits because we don't need more than the allowed information to compose a new verse. When there is too much info submitted, it makes it difficult for the artist to choose what to put into the song and can cause customers to ask about small details buried in paragraphs of details.
