Just a heads up for musical artists who are looking to promote their tunes on Spotify as well as for people running niche playlists who want to promote that list, there’s a place for that.
The Spotify Community is a message forum area devoted to the Spotify platform, covering a lot of areas of the field including playlists. The Playlist Exchange is the specific forum in the community where playlists are promoted and curators look for new songs to add to their lists. Many music genres get covered, but so do many niche areas such as topics, moods, musical arrangements and what have you.
Mind you, the Exchange may be an avenue for promotion but it doesn’t guarantee songs getting added to playlists or people actually following a playlist you post. I’ve submitted music by little known groups to playlists (songs by artists I am not associated with, I’m just a fan of) and got passed over while I’ve also posted my Underexposed Soft Rock and Easy Listening list with little gain.
Marketing is a chore. The Playlist Exchange is simply a potential contributor to goal achievement.
