Arielle Vaniderstine, a developer advocate engineer at Spotify, has made a new tool available called Nelson that puts the streaming service’s curation controls in your hands. Link up your Spotify Premium account and you can toggle the sliders for the various possible music traits to get a playlist immediately generated in your browser or Spotify client. Interesting personal hack/concept by this Spotify engineer. I am however having some unknown issue getting to work in my environment. Genre selection is blank on the overlay window. Firefox/Chrome/IE = No Love ??? Source Code @glitch Would be interested in other's experience getting it to work.
