Once you have finalized your release and submitted it to us for review, we do a quality check, which usually takes around 48 hours on weekdays.
After passing our quality check, the release is sent to stores. In theory, it can take 4-6 weeks for a release to become available everywhere. Unfortunately, we have no influence on the individual processing speeds of the stores.
Most stores, however, are much faster: iTunes usually takes about 2-3 days to put a release online, while Amazon, Spotify and Google usually do it within one week.
The stores can best comply with a future release date if you have scheduled it far enough in advance (no less than 4-6 weeks).
