NEWSFLASH mens brains aren't wired the same as each other's either, not to mention how different our cultures, social groups, GENERATIONS are. That alone doesn't give anyone the solid knowledge about gender likes and dislikes you claim to have. That being said, I know that the chance of seeing a music LEGEND like stevie wonder perform live is a much bigger deal to him and myself than it is to others. As a matter of fact it was a MALE friend of mine, let me repeat- a MAN, who won tickets also and told me to enter the contest in the first place. Making generalizations like that, that "men don't like that stuff," is simply unfair to everyone because how can you know what other people you've never even met before like? You're not being helpful or honest, you're talking about things and people you have not the slightest clue about. Country music might not be big news in Virginia (i'm not insulting, I simply grew up there) but here in new york we just got our first country radio station. Just a 6 hour drive away there's a totally different culture. Think about that.
Also I suggest you go to globalcitizen.org and learn a little bit more about this event and organization and what it means other than "oh john mayer is playing that means it sucks." you might even make a difference.
