This script repurposes the Spotify logo button on the Spotify website to play a random album from the your Spotify library. It fetches your saved albums, selects one at random, and starts playback.
Run the code in a tab with https://open.spotify.com/ open, using either the JavaScript console (Dev Tools) or a bookmarklet (code below).
After running the code, use the Spotify logo button to play a random album (or run playRandomAlbum() as required).
- Open Spotify in a web browser, whilst playing music in Spotify on a device e.g. your phone
- Open the Dev Tools (F12) and go to the JavaScript console
- Paste the contents of index.js in
- Click on the Spotify logo to trigger the random album feature
- The code works if you're playing music in Spotify on a phone/tablet but not if you're using the web site itself to play audio.
To run as a bookmark in a tab with open.spotify.com open:

- Maybe add a button that adds 5 random albums to the queue
