How to Release Stream-Only Music
Not wanting to distribute your music to sites like Amazon Music (Mp3 Store) and iTunes? You can set this up yourself. Here’s a step-by-step process on how to avoid sending your music to download sites.
Go to Catalog → Rights → Release Rights (or click Set Release Rights from the Release Summary).
Disable Download at the release level and click Save.
Distribute the release to iTunes/Apple Music and Amazon Music as usual.
The release will then go out as streaming only.
