Autoplaylists - called “smart playlists” in iTunes - allow you to create playlists that always contain songs matching some set of rules. For example, you could create a playlist that contains only music you haven’t listened to recently, or your most-played songs of a certain genre.
They’re one of my favorite ways to listen to music, but have never been available in Google Music. So, I’ve created a Chrome Extension to add them. Here’s an example of one of my autoplaylists:
If this is something you’ve also found Google Music lacking, you can download it at https://autoplaylists.simon.codes. There’s a free version limited to one playlist, and a paid version supporting unlimited playlists.
The code is also open source, and can be found at https://github.com/simon-weber/Autoplaylists-for-Google-Music. Check it out and let me know what you think!
