IMHO Madame X is her worst album. Very few songs I really enjoy.

I love American Life album, one of my favorites. On the other hand, Madame X is my least favorite album. I can't connect with any of the songs and I don't listen it for years. 

If they only had more contrast. I realized that is what made most of Madonna's albums great. She always made sure to have accessible songs next to more experimental and moody stuff.
Of course, I am not talking about her debut, LAV, and TB. And COADF was an exception. 
Take Music for an example. If it was full of songs like Nobody's Perfect and Paradise, it wouldn't have been the same great album. It would have been very moody and not that enjoyable, like Madame X. 
But if you add Music and other more accessible stuff, then you are being able to bop to its catchy songs and appreciate edgy songs. That is the formula that Madonna should use.
 
HC, RH and MDNA should have had more experimental stuff. Simple as that.
And Madame X could have been such a modern classic. I was thinking about her Latino songs and thought it would have been cool to have an album with such songs, then I was like "Oh, wait, she did Latino inspired album which is Madame X". If only she added more friendly and melancholic pop stuff like Who's That Girl, Madame X could have been different.
If you can't imagine it, then just place her old classics next to Madame X songs and pretend they are new songs. Suddenly, everything on it pops. It makes such a difference.

P.S. Yes, I am aware that Madame X had some friendly songs and that other albums had some moody stuff, but they needed more of that to achieve a perfect balance.
