LiveOne subscriptions cannot be downgraded directly from Premium to Plus.
If you currently have a LiveOne Premium subscription, and would like to downgrade to LiveOne Plus, the only way to do this is to cancel your current LiveOne Premium subscription and wait for your current subscription to end. Once the subscription has run through the remaining portion of your subscription and your account returns to a free Basic account, you can purchase a new LiveOne Plus subscription.
To cancel your Premium Subscription: Cancel a LiveOne subscription
To purchase a new Plus Subscription: Purchase a LiveOne Plus subscription
Note: All custom stations and favorites are saved to your account. Nothing is removed from your account when the subscription ends, so you will not lose any of your music.
