Hey Madgefan -- LiveNation did not OBVIOUSLY buy Madonna. You don't think Madonna has ANY say in how much she charges for her tickets? She does. She's an enterprising business woman who has controlled her own career from day one and if you think the price of her tickets is any different, you need to wake up. To put it in perspective, U2, another act that are touring superstars, are not only on tour under LiveNation right now and are managed by Guy Oseary, but they have GA seats on the floor for their concerts starting at $45. So, if an act that was "bought" by LiveNation wants to control their ticket prices, they can. Madonna is no different.
I don't necessarily think she's overcharging for $400 floor seats. I've paid that multiple times and she's worth it. But, now paying $400+ for seats that went for $250 in the upper bowl on the MDNA tour or $175 for sitting practically behind the stage for The Rebel Heart Tour? Not worth it.
