Chile apples vs oranges. Again, Janet in comparison to Superbowl performers governed before Pepsi took over slays.
Madonna did the Superbowl in 2012... Almost a decade after Janet. Of course technology would be better. I would not compare the MTV era to the Pepsi era. For Pepsi production Madonna's performance is not on the level of Katy, Beyonce, JLo/Shakira, or Gaga. It is more comparable to the earlier Pepsi era - like Prince and Black Eyed Peas.
