Last week, Spotify announced some changes in how their editorial playlists work.
From now on, Spotify will begin to personalize some of their editorial playlists, meaning that listeners will hear individual versions of those playlists tailored to their own musical taste. This will make editorial playlists even more important, as in addition to getting your music in front of lots of listeners, they will now put that music in front of listeners who are specifically looking for it.
