We do not register your music BMI or ASCAP. You also don't have to after you distribute your music through us.
You don't need to be registered with a Performing Rights Organization in order to collect your earnings from the streaming services you distribute to via DistroKid, but you're welcome to do register your works with them for additional publishing administration outside of DistroKid.
We don’t yet offer admin publishing services. However, many DistroKid artists use SongTrust for publishing admin, and we love it! We’re working on a publishing admin system for artists. But in the meanwhile, check out https://songtrust.com.
