Artists usually pay for a bio link, then a smart link, then somewhere to send the promo. it's out now is all three. A free bio page. A page for each record that takes fan emails before release day and fills with listening links when it's out. A private page for each writer or DJ you send it to, with their name on it, so you see who pressed play and how far they got. The links get checked every day. One login, instead of a Linktree and a DISCO.
