If you want to remove stores, you can do this:
- Delete from all stores.
- Immediately after Step 1, re-upload your album--but choose only the stores you want
Because stores take the same amount of time to delete albums as they do insert new albums, you'll have minimal overlap; your old release will be deleted around the same time your new one is inserted.
If you have a bit of overlap (where multiple versions of the same song are in stores at the same time), it doesn't cause any accounting problems or otherwise.
If it's totally not possible for you to delete & re-upload, just drop us a line and let us know which stores you want to remove. Note that this method may take a little longer (up to 2 weeks).
