What if someone buys the exclusive rights license after I already bought a non-exclusive rights license to the same beat?
Nothing. As long as you made the purchase before the exclusive rights being sold off, all your rights remain intact as described on your certificate of licensing. However, you will no longer be able to purchase additional rights to the same beat if the exclusive rights to it has been sold. We encourage you to buy the exclusive rights as soon as you realize you need such rights due to this first-come first-serve policy.
