Unfortunately we have no influence over what songs are promoted on the front pgaes of our distribution partners, and cannot offer any store promotion as part of the Spinnup service.
To get your music in front of the eyes and ears of music fans we recommend you try DIY playlist marketing and contacting the curators of prominent playlists to pitch your music for a spot on their lists. The more playlists your music is added to, the more likely you are to be featured in Spotify's Discover Weekly, Release Radar and other playlists. Sometimes one good playlist placement is all it takes for an artist to get discovered!
