If you’re a Google Music user, there’s a good chance you’re using the service on your computer. But if you want to disable the service, there are a few steps you can take. First, open up your Google account and click on the “Settings” button. Then, under “Google Music,” select the “Disable” option. Now that you’ve disabled Google Music, be sure to sign out of your account and then re-enter your password so that your music is still accessible.
