We offer a 30-day free trial when signing up, and your subscription will be automatically renewed once the 30 days are over. In order to make sure there is no disruption with the music due to payment failure, we try to reserve the cost of your Soundtrack subscription a few days prior to the renewal date.
Please note that reserving an amount doesn't mean we actually bill you, the subscription cost is merely reserved to ensure the payment goes through on the renewal date.
You can always cancel the subscription at any time before the renewal date. If the reservation has already been made, it will be automatically released. If you want to know the date on which your subscription will be renewed you can always log into your account, go to Account settings on the top right drop-down menu, click on subscriptions and look under renewal.
