Apple Music is finally here, along with a free three month trial to let anyone give it a listen. But what if you don't want to be on the hook for a $10 a month subscription fee on September 30? Or, what if you opted into Apple Music by mistake (which is surprisingly easy, since it's the first thing that pops up when you launch the iOS Music app)? Well, you can just disable auto-renewal, just like any other iTunes subscription. To do so, tap the "Account" icon on the top left of the Apple Music app and navigate to View Apple ID (alternatively, you can get there from the iOS Settings app and heading to "iTunes & App Store"). Once you're at your Apple ID settings screen, tap "Manage" under subscriptions, then "Your Membership" and untick the auto-renewal checkbox at the bottom. You'll still be able to test out Apple Music for the next three months, you'll just avoid any surprise charges.If you're on a PC or Mac, you can also disable the Apple Music subscription from iTunes. Simply click the "Account" icon (it looks like the head of a person, right beside the search box), and go to "Account Info." Under the "Settings" section, find the "Subscriptions" line and click "Manage." Then all you need to do is click "Edit" next to your Apple Music subscription and click "Off."
