Periodically, Harmonix delists songs from the Rock Band Music Store due to license expiration. As with most music licensing agreements, Rock Band's licenses for DLC have fixed terms on how long content can be sold on the platform. Harmonix announced that they will attempt to renew their license agreements, promising to give players advance notice if certain songs cannot be relicensed and must be delisted. Songs removed from the Rock Band Music Store are no longer available for new purchases; however, users who purchased songs prior to their removal from the storefront are not affected in their ability to use the content, including re-downloading songs if necessary.
