I loved Erotica when I bought it (still do), a bit scandalized by it at such a young age. A few quibbles: Only 3 of 7 Madonna albums had gone to no. 1 at that time. And she had some genuine successes later, Ray of Light and Music both outsold Erotica... and by today's standards Erotica would be a huge hit. I recommend the non explicit version, because the regular version is the same, but lacks a terrible attempt at a rap song, "Did You Do It?"
Excuse me, the "end of the pinnacle of her fame"? Were you asleep during the ensuing decade in which Ray Of Light, Music, and Confessions On A Dancefloor came out?
