Do I have to have signed contracts with authors?
Sundesire Media don't check the your agreements with 3rd parties, but by default the client need to have signed all licensing agreements with the authors of the published music. In case of receiving claims of infringement of rights from third parties, we have the right to request documents from the client, as well as takedown the release and / or block the client's account.
If you are the author of a work and have not used other people's samples, do not release cover versions or remixes of other people's tracks, then contracts are not required. In case of release cover versions or remixes, supporting documents for the right to release are required.
