You're able to use TuneRegistry if you're not a member of a performance rights organization (PRO). At the core of TuneRegistry is our robust music business catalog where you can manage your songs, recordings, and albums regardless of your affiliation with performance rights organizations (PRO). Additionally, even if you are not a member of a PRO, you can still register your metadata with our metadata exchanges and take advantage of other features of our registrations module such as getting ISRC codes.
