When you create playlists in Apple Music, the service lets you use custom cover art. You can choose a photo from your library or one of the covers the service generates. I usually opt for the latter, but over the past few months I’ve grown tired of Apple’s playlist cover options: choosing from the same half-dozen templates gets boring after a certain point. That’s when I discovered Denim, an app that lets you create custom covers for Apple Music playlists.

Denim has been around for a few years now and recently got a major update that added a lot more cover art options. The developer also created Hezel, which lets you back up all your Apple Music playlists.

When you open Denim, the app will ask for permission to access your Apple Music data. This is required so that the app can see your playlists and help you generate album art for them. Once you grant this permission, the app will show you all of your playlists in handy sections. One of these sections highlights all playlists with one of Apple’s default covers, and the other shows you playlists with a custom cover.

This makes it easy to find playlists with old cover art. It’s also nice that the app only shows custom playlists that you’ve created. This saved me a lot of trouble, as I have about 200 playlists on my Apple Music account, including about 50 that I’ve created myself. To start creating a cover, tap on one of your playlists and Denim will generate a bunch of covers. There’s a good variety of basic covers with a solid background color and some with gradients and textures in the background.
