DistroKid

DistroKid is a software platform that helps musicians and other audio creators get their music into major digital stores and streaming services. Its core job is to take the practical work out of digital distribution, so artists can upload tracks, manage releases and credits, and keep their catalogue available across multiple services without having to negotiate separate deals or handle complex delivery requirements themselves.
