OK, replaced the code with the 3 new songs and much much happier with the game now.
War Machine -> Girls got Rhythm
Hell Aint a Bad Place to Be -> Dirty Deeds Done Dirt Cheap
Let There Be Rock-> Shoot to Thrill
Live Encore Song -> Long way to the Top
So the difficulty in making the change is 4 fold,
#1 New song has to fit into the same time duration as the old song
#2 Song has to fit into the theme of the old song
#3 Song Title has to fit into the Jukebox light hole slot
#4 Song loop during the song select has to be the same length.
So how do they rate in these 4 areas
#1 Perfect, I have heard 2 of the songs from start to finish and they end at the right time and there's no delay in restarting don't know on the third one yet
#2 So-So. Probably should have put Shoot to Thrill into War Machine and something with Rock in the Title for the rock targets. I would like to replace Rock and Roll Train as well, but there is no other ACDC song that would tie into the large train.
#3 Two perfectly fit into the cut out slots, Girls got Rhythm is a little long.
#4 This is the least important to me of all of the other criteria which is good because none of the loops work very well. Dirty Deeds almost works but is a split second off. Girls got Rhythym cuts off mid lyric.
One thing I never noticed is how "Let there be Rock" is so frequently played as the end of game music or enter your initials music, but I definitively notice now that it's Shoot to Thrill.
