While there are releases of artists I've never heard before are in my Discover Weekly playlist, there are missing essential releases of artists I often listen (Young Fathers, David Byrne and Editors). Is this because some artists pay to get promoted in the lists? Please make sure listeners get to know the right releases, because it's the only service for new releases you facilitaire.
Discover weekly is for you to discover music new to you. The music on discover weekly does not have to be released, but has to be in a genre and related to music you usually listen to, but with different artists. It is suppose to help you find new music to you and helps expand the genres you listen to.
