I've included some brief notes. I'm typing on my mobile so please excuse any spelling/grammar mistakes sisters 
Madonna | 4/10 (I don't want to be to harsh because it's the Queens debut...)
Like A Virgin | 5/10 (the singles are the only good songs)
True Blue | 10/10 (pop perfection)
Like A Prayer | 9/10 (I would have to swap Love Song for Supenatural to give full marks)
Erotica | 10/10 (underrated, experimental, innovative and gritty. This album transports me to another world, the darkness of club life in New York City. Rain is one of the most flawless ballads I've ever heard, each song tells it's own anecdote like an indepent film.)
Bedtime Stories | 8/10 (extremely cohesive, and shows a more warm and welcoming Madonna than Erotica)
Ray Of Light | 10/10 (enough said)
Music | 6/10 (same problem as LAV, Amazing slays tho, WIFLFAG gave the album an extra two points)
American Life | 5/10 (Nothing Fails is the album's highlight. DAD, LP and Hollywood are very good, too self-focused. If it had more songs like "Borrowed Time" would make the album better)
Confessions | 7/10 (first half slays, second half sans Push is okay at best)
Hard Candy | 5/10 (mostly rejected Nelly Furtado demos, lacks innovation, I despise Justin Timberface and his sounds pollutes the album, the singles are good + Candy Shop, Heartbeat and She's Not Me)
MDNA | 6/10 (Has great foundation for what could have been a flawless pop album, Gang Bang is the highlight, GMAYL was the best choice for first single, lacks emotion and personal context, poor mastering and vocal processing)
Rebel Heart | 8/10 (lacks cohesion but kinda works in it's favour, personal, innovative, diverse. There's something for everyone. Ghosttown, LFL and Devil Pray are the highlights.
Rebel Heart's score may increase or decrease depending on how I feel next March.
