When you first set up Apple Music, it asks you to input some genre favorites and pick some favorite artists. When you’re first launching the app and want to check things out, it’s pretty easy to ignore that and move on. Thankfully, you can head back and redo the configuration.
All you need to do is tap your Profile > Choose Artists for You in the Apple Music app (or iTunes). From here, you can change your genre selection or pick new favorite artists. You can also start over completely from scratch by tapping the Reset button. Hopefully, doing so will improve Apple’s recommendations and make your listening experience a bit better.
