BigLock,
I use music to enhance the mood. i play the NFL music because it sets the tone. the most hysterical part of it, is when i put it on, my son comes running to the table because he knows its "foobal" time

.
i also plan to hook up small ipod speakers to my stadium (when i finish building it) and booming music while i play the game. i really want to coordinate that so the music drops in between plays with crowd noise during the plays. i have a whole schemed out plan for the music as it will play a huge role in my stadium game play.
as far as the hip hop goes, when i am working on some aspect of the EF hobby (while my son is asleep), i enjoy "Top Down" - Swizz Beatz. i loop it over and over.
PM your address and i can make you a copy of my NFL cd. complete with a cool Monday Night Football theme remix. LMK.
Scott
PS How many of you guys quickly think Martin Luther King when you see LMK in an email? i sure do.
