- When: 2022
- Who: Me
Don't send your old playlists to landfill! The Spotify Playlist Recycling Plant is a sustainable solution that combs through your music library and generates new intelligent playlists based on a few user inputs.
If you're anything like me, you've got thousands of songs floating around in a bunch of Spotify playlists with titles like "~~GUD S0NGZ 2k18~~". You know there are some forgotten gems in all that mess but it would take ages to find them...
At the heart of this tool is a custom algorithm that uses Spotify's 5000+ unique genres to identify similar artists. E.g. If you want to listen to some tracks that sound like The Stooges and The Ramones, just plug in those artists, adjust a few settings and your playlist will be ready before you can say "The KKK Took My Baby Away".
- Select your pre-loved playlists: You can choose any playlist you follow or have created.
- Customise your settings: Adjust the time period, artists, genre etc.
- Profit: Export your shiny new playlist directly to Spotify.
It's pretty simple. You'll work it out.
This tool was built using React.js and leverages Spotify's Web API. I decided to make this a client-side app for simplicity.
