Apple Music pre-adds are subject to a few conditions, unlike Spotify pre-saves:
- Your product must be live on a pre-order period.
- Your product must have at least one Instant Gratification Track setup.
Apple Music is a streaming service, and doesn't support pre-orders. An Instant Gratification Track being setup means the one track will be streaming on Apple Music, so there will be a product page live on the service. Once the product page is live then the pre-add feature becomes available. Even though the product page will only show one track (or however many Instant Gratification Tracks you have setup) the pre-add is for the full release. Once the pre-add has been used on a product, the product will appear in the user's library on the day of release.
You can setup a pre-order period within the uploader. Our Instant Gratification Tracks article goes into detail about what they are and how to set them up.
