Amuse sends the music to the stores after we have done a quick check to ensure that your release will be accepted everywhere.
We go through the uploads according to the release date chosen in the app but we try to get also to uploads weeks or months away done within a few business days as well.
Your release needs to be delivered to the stores at least 5 business days before your release date for Spotify and iTunes/Apple Music. To get your release out on a Friday (New Music Fridays!), upload on Wednesday the week before, at the latest. This also gives you enough time for the release to show in your Spotify for Artists app where you can pitch for playlisting of not yet released material (read more here).
