Fortunately once you're as big as Madonna is the chart positions don't matter so much. She'll always be the one and only Madonna, and as someone that has followed her since 1982 she's making some of her best music EVER right now with this album. The music industry has just changed so much, and is so fragmented it's going to be hard for there to ever be anyone as big as Madonna in the music industry ever again. The big record companies will make sure of that.
Long live Madonna, and long live Rebel Heart!!!
