Guys... Can you save the arguing for the actual game? 
Metallica songs that are surely* eligible for TJST are The Unforgiven, Nothing Else Matters, The Unforgiven II and The Unforgiven III.
Iced Earth songs that are surely* eligible for TJST are I Died For You, A Question Of Heaven, Melancholy (Holy Martyr), Watching Over Me, Consequences, Blessed Are You, Ghost Of Freedom, When The Eagle Cries, A Charge To Keep, Harbinger Of Fate, Anguish Of Youth, End Of Innocence and If I Could See You.
*Maybe some other songs I missed.
I haven't yet decided on the criteria and the game format though.
