Hey Chase,
sounds like you are doing some good stuff. First, I'll add my two cents on what the stadium music should include.
You should be able to set your own stadium music for every point in the game like you could in nfl 2k5. It literally had a menu that had you select the occurrence and what song would play. This needs to work both online and offline and in online franchise. Any time you play a game. Every occurrence in the real NFL that would play stadium music should also be included in Madden.
ON a second note, when are we going to be able to provide feedback for gameplay related items? I have a lot to give on that front
