Yes, you can.
*If the release is delivered to or already in stores, this is how you do it:
1. You do a new and complete upload with the new artwork in the app. If you have released the music before, make sure to reuse the same ISRC codes.
3. The new release will go through the same approval process as all the other releases with Amuse.
4. When the new release with the new artwork is out in stores, you contact support and ask us to remove the first release with the old artwork. Remember to email us from the email address on the account it is regarding.
*If the release is Not Approved because of an issue with the artwork, you can replace the artwork in the app. Make sure that you have the most recent version of the app.
*If the release is In Review, delete the release and do a new upload with the new artwork.
