I actually have Madonnas entire catalogue of songs. When you look at the amount of hits and number of classic ballads, classic pop songs, classic club songs etc etc its actually astonishing.
Then you have Gaga with her one note sound. A sound which actually belongs to Redone. She may well go on to create a more diverse catalogue of music over the years but so far she's a one note wonder.
And her little monsters can go follow each other off a cliff.
