Why can the NBA get its act together for a halftime show but the NFL can't for the Superbowl?

Why is it the NBA can put on a good show for its All Star halftime but the NFL can't for the Superbowl and the biggest game in the world? Seriously who the hell cares about The Who? No one. Why doesn't the NFL get someone relevant like Jay Z, Shakira, Kanye West, Beyonce etc. If the NBA can pull it off so can the NFL. Shame on you NFL I'm actually sitting here watching the All Star halftime and Shakira was smokin hot.
