Show HN: Recycle your old Spotify playlists into new ones
22 by dr00bot | 3 comments on Hacker News.
I wanted a way to quickly generate new Spotify playlists from my library based on some simple user inputs. There are probably a bunch of songs floating around in old playlists that you will never listen to again so the Spotify Playlist Recycling Plant is an attempt to resurrect these forgotten gems! At the heart of this tool is a simple custom algorithm that uses Spotify's 5000+ unique genres to find similar artists. It works well for my purposes but everybody uses Spotify differently so I'd love some feedback :) Built using React and the Spotify Web API.
