What is Publishing Royalties?
In regular music there are many people taking part in the creation of track. There are composers & authors of lyrics (Publishing rights) and vocalists or musicians who performed to create the record (Neighbourhood rights).
In electronic music everything is easier, we create it ourselves, but the industry still works by the major rules. And retailers like Beatport, Spotify, YouTube, Facebook or even the clubs and festivals hold Publishing and Neighbourhood royalties which is getting lost if the artist doesn't have the General Publishing contract.
The Publishing company is able to claim that revenue and pay it to artist.
