For those claiming Madonna can't sing.....
....... Here are two videos proving she can sing very well. Madonna has an unmistakable voiceprint, her voice is versatile and applies to various music genres and has got many different nuances and as the videos stress, her voice is powerful too!
Look, the vocal range values may be imprecise but what these videos are meant to highlight is that Madonna is actualy a good singer with an uncommon voice.
