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 but we try to get also to uploads weeks or months away done within a few business days as well.
To get your release out on a Friday (New Music Fridays!)upload on Thursday the week before, at the latest. You need 5 business days after uploading to releasing in stores (if everything checks out).
