I have noticed that the music doesn\'t play all the time, it seems to me more of an intuitive situational music. Which I personally like over the other games nightmarish overly loud \"Nintendo\" (the original in the 80\'s) style arcade music. Once through the average games music and I am reaching for the mute.
I also feel that the music score seems a tad longer than the \"other guys\" music, which means it has more variety before it repeats.
I might just have lucked out with the perfect sound card for this game, sure is nice if this is what happened.
