Alright everybody, For the main pop girls who've been around long enough to put out 5 studio albums (excluding holiday albums or live albums) who's is your favorite?  The 5th album for many pop girls is a standout in their discography.  Forget about commercial success & charts- and put only music quality into consideration, as well as era visuals and performances/music videos/photoshoots! Which album/era is the best? CHOICES: Erotica (1992) - Madonna Butterfly (1997)
