First I'd strongly suggest you change your password. You can do that on this page (Note: if you account is linked to Facebook change your password there). Then you can use the button 'Sign out everywhere' on this page and all the devices connected to your account will be signed out. You'll have to relogin on every device with your username and new password. Your account is now secure and you can now continue to enjoy uninterrupted listening again!
Good luck and have a nice day! 🙂
