Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
Nice box set with the extras in CD format. The vinyl was pressed perfectly. One of the best sounding records I have. Wish they would do this with a collection of music from Tyranny for you. Maybe in the future if Sony doesn't still hold the publishing rights and hoard them like they do with many artists.
