Nice review! Thanks for posting.
I just want to say, Papa Roach would play Dead Cell if they had more time to play and if they were headlining or co-headlining. Both times I've seen them live (in the summer of 2010 and in January with Stone Sour) they have played it.
According to someone who attended the Clarkston show on setlist.fm, the songs you missed after you left were Second Chance. Simple Man, and Bully. It's a shame they dropped 45 at your show and for the night after. Hope they put it back in the set, so there is at least one old-school Shinedown song in their set.
