Streaming services don't take songs straight from musicians or from apps. Independent artists release through a distributor: a service that sends your song to all of them at once and passes on what it earns. Blackcap makes the file they need; you choose the distributor.

  1. Finish the song and listen all the way through, on headphones and on a speaker.
  2. Finish & Share (on the Song page, or in More) → Full-Quality WAV, with Release-Ready Loudness on. It brings the song to about −14 LUFS, where streaming services play songs, and tells you what it did.
  3. Tap Share or Save and save the WAV to Files.
  4. Make cover art: a square picture, at least 3000 × 3000 pixels, with no web addresses or logos of the stores on it.
  5. Choose a distributor (search for “music distributor” to compare a few). They differ in price (a yearly fee, a fee per release, or a share of what the song earns) and in what they keep, so compare them first.
  6. Sign up, upload the WAV and the cover art, and fill in the song's title, your artist name, who wrote it, and a release date. Most ask for a date two or more weeks away, so there's time to get it onto every service.
  7. Once it's out, claim your artist profile on each streaming service, to add a photo and see who's listening.
