Im Music Producer, DJ, Label owner.
I can upload on all essential streaming services: Spotify, Apple Music, Deezer, Tidal, Pandora.
Also on YouTube, Google Play, Soundcloud... and if you like on download sites like Beatport, iTunes, Juno, Traxsource.
You would be the owners of everything on the distribution (a third party). I would be just a manager to put it all up.
