Lemonade and ANTI... honestly I've only listened to the albums once or twice in full so I won't judge them too harshly.
Dangerous Woman deserves like an 80-ish score. 78-82 range. But 76 is cute.
Glory deserves like 75-78 imo.
Joanne... I haven't listened to it yet either but from PI, Million Reasons, A-YO... I can't say I'd give it more than 40...
I was in the exact situation as you before listening to Joanne, I hated it based on PI. Now that i've listened to it I'd give it an 80 at least. Those three songs probably are the worst ones on the album.
The Lemonada score is okay. It shouldn't be lower than 80-85 anyway.
Anti was a little bit too low, a few points more would have been decent.
Britney's should have been in the range of 65-70, so it's rather fairly rated.
Gaga shouldn't be over 50
