DistroKid is constantly working to ensure that our users are only uploading content they have 100% rights to, but sometimes people stink. 😡 If someone has uploaded your music/photos/artwork to DistroKid without your permission, please reach out to us with a link to the release, and we'll get you in touch with our Claims Department.
Under Something is Displaying Incorrectly in Stores - Topic, please select "I want to submit a Copyright / Trademark Infringement Claim".
If someone has uploaded your intellectual property outside the scope of DistroKid, that's unfortunately not something that we can help with. BUT, you can also reach out to each streaming service with a DMCA takedown request. You might need to Google around for each service's process, but here are some we're aware of:
