If your music includes cover songs or samples, you'll need to obtain the necessary mechanical licenses from the appropriate rights society before production can start.
You should check with your local licensing society in your country to ensure your rights are protected when reproducing music on a physical format. Each country has their own music royalty collections, licensing and rights societies.
If you and the group are 100% the creative owners of all the music, we can supply a general Intellectual Property Rights declaration form.
If you live in France, we will need your SDRM authorization, no matter if you have cover songs or samples or not.
