15 Rainbow - Rising +3
13 Judas Priest - Screaming For Vengeance +2
5 Queen - A Day At The Races +1
2 Judas Priest - Killing Machine
1 Black Sabbath - Technical Ecstasy
Rising is such an iconic and pure metal cover, bring on the fantasy! Screaming For Vengeance is so captivating, I guess because of the colors and the (metallic) eagle. Somehow eagles on a metal cover always work. A Day At The Races looks like a coat of arms, so it's noticeable.
I've never been a fan of the Killing Machine cover. Technical Ecstasy is weird.
