He said that a pre-save the album on Spotify link helps juice the rotation placement when the release actually happens, then as many likes and listens as you can beg from friends and family can keep it going.

That said, he made $3 since the release. It's a hard road, I wish you the best in your attempt. Music can be so fulfilling.

Edit: found the marketing company he used: https://www.show.co/ They set up the Spotify stuff for him, and other things. Then he has a web site, Instagram, etc.
