Every artist wants to appear on one of Spotify’s playlists since it adds instant credibility and streams as new people find you. It’s never been easy to crack one of these playlists, and the service is about it make it a little harder with the new “personalized playlists” that it will be rolling out soon.
Personalized playlists are basically playlists that are customized to the taste of every Spotify user. They feature a set of songs that comes from the curator team, and a number of tracks based on individual listener habits that are determined by an algorithm. What that means is if you finally break into that playlist that you’ve been trying so hard to get on, your song still might not appear on everyone’s version of that playlist, since they’re now customized per listener.
