I kinda grew up with that album not knowing it was Madonna's.
When I listened to it a few years back I remembered every song on it and it just gives me a very happy and soothing feeling whenever I listen to it. No other album does that to me.
Oh the others would be Daft Punk's Discovery and deadmau5's Random Album Title.
As of now
Born This Way, The Electric Lady and Visions
Runner ups: True, B'Day, Love.Angel.Music.Baby, The Sweet Escape, The Dutchess, Electra Heart, Push and Shove, Shakira Grandes Exitos
So many runner ups but I can't just have 3 on there
My 3 favorite albums of all time, all equal in perfection
No Doubt - Return of Saturn
Björk - Vespertine
Fiona Apple - The Idler Wheel is Wiser Than the Driver of the Screw and Whipping Cords Will Serve You More Than Ropes Will Ever Do
