We recommend scheduling your release out for whatever amount of time your digital distributor recommends to space out for them to get it to all of the platforms.
Additionally, we highly recommend releasing your upcoming release on a Friday at midnight. To be completely specific: Midnight Friday is the very first minute of Friday. Midnight/12am Friday is one minute after 11:59pm Thursday.
Releasing Friday at midnight is industry standard. It’s also when Spotify editorial playlist curators and user playlist curators most commonly update their playlists.
