If you all use different scales with your reviews that's an issue haha. People understand reviews are one person's opinion, but a consistent rating scale across the website would be beneficial.
When everyone used the percentages back in the day 50% was about as bad as it could get, because even if a reviewer didn't like a record, they couldn't pretend all aspects of it were bad. Their overall impression of a record (the 'tilt') was only one small part of the final score. A band with great musicianship, a great singer and great production would instantly deserve a 9/10 inthose categories even if the songwriting and lyrics were horrible.
