Playing a Random Album on Spotify

I still like listening to albums and sometimes want Spotify to play a random album from a playlist of albums I’ve created.

I couldn’t find anything out there that does this so I wrote myself a script to handle it instead.

Here’s a rundown if you want to use it.

First up, you’ll need a playlist with at least one track from each of the albums you want to choose from (here’s mine). Grab the ID of your playlist1, and your username and add them into the script below.

Then, you’ll need to create an app in Spotify and get your client ID and secret, add them to the script below, so you can authorise the script.

Finally, run gem install rspotify in your default ruby2 and you should be off to the races.

Run the script with Spotify desktop app installed and it’ll open up a random album for you to press that sweet, sweet play button on ⏯.

I run the script from an Alfred workflow so I’ve got it close at hand.

Enjoy 🎷🎶

#!/usr/bin/env ruby
#/ Usage: open-random-album
#/ Open a random album in Spotify.

require "rspotify"

class RandomAlbum

  def self.fetch
    RSpotify.authenticate(CLIENT_ID, CLIENT_SECRET)

  # Grab the albums from a playlist and choose one at random
  def fetch
    playlist = RSpotify::Playlist.find(USERNAME, PLAYLIST_ID)


  def tracks_in_playlist(playlist)
    limit = 100
    offset = 0

    [].tap do |result|
      loop do
        tracks = playlist.tracks(limit: limit, offset: offset)

        break if tracks.empty?

        offset += limit

  def albums_in_playlist(playlist)
    tracks = tracks_in_playlist(playlist)
    tracks.reduce({}) do |acc, track|
      acc[] = track.album

album = RandomAlbum.fetch

puts "Opening '#{}' in Spotify"
system "open #{album.uri}"
  1. Click on Share -> Copy Spotify URI. The playlist’s ID is the string after the last colon. 

  2. If this becomes a pain I guess you could look into bundling the script up with its required gems somehow. 

Better Kindle Reading

I read the majority of my books on my Kindle. The Kindle’s convenience is pretty hard to beat and I enjoy its highlighting and note-taking features.

With that said, I find I miss the context that a physical book provides. It’s much easier to breezily flick around a physical book to find previous sections you’ve read or peek ahead to see what’s coming up.

Recently I fired up the Kindle for Mac and found that I can get better context and a view of my highlights all at once. Open it up in widescreen, open the contents and notes and highlights sidebars, and boom baby, you can see a summary of where you are in the table of contents and what passages you’ve highlighted or bookmarked on the right.

I find this arrangement particularly helpful when reviewing a book I’ve previously read. Have a crack yourself, see if you like it.

Finding Open Web Pages with Alfred

There are a handful of web pages that I use regularly throughout the day. Some are web apps that I keep pinned in Chrome while others come and go as I work.

I tend to close tabs when I’m done with them but I still end up with many open tabs. I’ve created an Alfred Workflow that opens a page I’m looking for so I don’t have to pick through my Chrome tabs by hand to find it.

The Find Page workflow takes a URL from a predefined list, runs an AppleScript that finds and activates the associated page if it’s already open in Chrome, otherwise it opens it in a new tab.
