To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Only one thing I have a problem with is that they advertise you have access to over 500 songs this is partially true. You have access for 1 month and then it’s required that you pay an ongoing subscription otherwise it reverts back to 100 songs. I find this to be misleading and it’s quite disappointing.
