Generally, yes, canceling an Amazon Music Unlimited subscription early may result in fees. According to Amazon's policies, you can cancel at any time, but you won't be eligible for a full refund of the unused portion of your subscription. However, if you cancel within 30 days of signing up, you can get a full or partial refund, depending on the type of plan you signed up for. If you've already listened to some content and want to cancel early, you might only receive a pro-rated refund for the remaining time period. It's always best to check your account details in the Amazon Music website or mobile app to confirm their specific cancellation policies.
