This list is kind of long but I would love it if they played ANY of the following (my favorite tracks including something from almost every album): 

ROCKA ROLLA
DIAMOND & RUST
VICTIM OF CHANGES
EPITAPH 
SINNER
DISSADENT AGRESSOR
STAINED CLASS 
BEYOND THE REALMS OF DEATH
HEROES END
DELIVERING THE GOODS 
HELL BENT FOR LEATHER 
BURNING UP 
BEFORE THE DAWN
RAPID FIRE 
HOT ROCKIN'
HEADING OUT TO THE HIGHWAY
RIDING ON THE WIND
FEVER 
FREEWHEEL BURNING 
THE SENTINAL
EAT ME ALIVE 
TURBO LOVER 
BLOOD RED SKIES 
PAINKILLER
TOUCH OF EVIL 
HELLRIDER 
DEMONIZER 
WORTH FIGHTING FOR 
ANGEL 
REVELATIONS
PERSECUTION 
I woud think METAL GODS would be appropriate to close

All of these songs really rock or they are just plain beautiful. I think I would cry if they played "Here Come the Tears" which is a big favorite.
