How can musician place his music within Nimses
Nimses only works with official labels. At the moment, Nimses works with the Zvuk platform. If you are a musician and you want your music to be available within Nimses, your easiest way to be on Zvuk (and on other music services, if there is such a desire) is to upload your music to TuneCore. It's a label and a service that you can use to manage your music rights.
