Here's how to cancel your Apple Music trial so you don't start getting charged tomorrow

Anyone could opt in to the free trial at any time by opening up the Apple Music app and signing up.

But in the fine print, Apple said that if you didn't cancel before the end of the trial, you would enrolled in its "auto-renewal" program and be charged $9.99 per month (or $14.99 for a family account). You will be billed to the same credit card you store in iTunes for buying apps or music.

If you were an early adopter, that three-month period will expire any day now, and it's time to decide whether you actually want to pay for the service.

If you are - unlike Google chairman Eric Schmidt - a fan of Apple Music, just do nothing and you'll continue to get access until you cancel. But if Apple Music didn't convince you, or if Spotify's focus on artificial intelligence just jives better with your music discovery tastes, you should probably cancel soon.

Here's how to turn auto-renewal off.
