If you chose Soundcloud as one of the delivery channels for your release, your release will be uploaded to Soundcloud, as well as the Soundcloud Content ID system.
If you noticed a duplicate of your release and you want it removed, you can either issue a takedown for specifically Soundcloud or you merge the release with your own version (to do this, contact us here).
