spotify-collage.pl takes a url to a Spotify playlist and stitches a collage of album art images of the tracks in that playlist.

• The album art images are resized to 200x200 pixels
• The images are laid out in a 4:3 grid
• The generated collage is saved in .png format in the folder that you run this script in.

Before you can use the script, you’ll need to set up anapplication on Spotify. This will give you a client_id and client_secret. You'll need to save these to a file called .api_keys in your home directory:

[spotify]client_id = <your client_id>client_secret = <your client_secret>

This script also has following dependencies that you'd need to install from CPAN:

• Config::INI::Reader
• Imager::Montage
• JSON::XS

You should then be able to run the script as:

perl spotify-collage.pl --playlist https://open.spotify.com/user/beatlesplaylists/playlist/1FbXE0DKfcNlIRexSEHcs8

I've only tested this script on macOS 10.12.3. If you have a working installation of Perl 5.14 or higher and are able to install the dependencies, itshould work on older versions of macOS as well. It might work on Linux with little or no tweaking but about Windows I am considerably less sure.
