What's wrong with having a concert in Omaha, Nebraska?

I love omaha but i hate that not enough concerts stop by to perform for us. Sure we've had a couple of big names like lil wayne, green day,christina aguilera, bon jovi, and nickleback (although not alot of people like nickleback), etc., but why are people like beyonce, jay-z, lady gaga, the black eyed peas, etc., going to places around nebraska? Is it because the quest center is too small, do they not have time on their schedule, do they not like omaha, or is it for another reason?
