Plus, a new feature called “enhance” allows you to retrieve recommendations within a playlist you’ve already created, and just this week, Stål said in a video presentation that the team at Spotify was considering an approach that employed a human editor alongside the machine learning algorithm to create audio experiences that could maybe mix and match songs with podcasts and others.
