Twenty-six critic scores contributed to You Seem Pretty Sad for a Girl So in Love’s Metacritic average.
Metacritic’s album score was 87 out of 100, and the Wikipedia article states that this weighted average was based on 26 critic scores. The number identifies the review sample behind the aggregate rather than representing a rating itself.
Review outlets do not all use the same scale. Some publications gave numerical scores out of ten, while others used stars or other systems. Metacritic converts those results into a comparable scale before calculating its weighted average.
This figure can be confused with AnyDecentMusic?’s review count. That site also compiled 26 reviews for the album, but it produced a separate weighted average of 8.5 out of 10. The shared count does not mean the two websites use identical methods.
