Bey made a fantastic visual album but I wouldn't put her career side by side with Madonna's and say Bey is the superior "visual artist." Madonna is almost untouchable in that regard.
It's not like this is demeaning Beyoncé. Nothing to get upset over. Madonna is a visual artist as well. The timing of these comments is very interesting though...
To be fair ALL artist use some form of inspiration. No one is truly original, but yes she did steal. Grace Jones said she would sit in the back of her concerts and take notes....
