Honestly, the only old hits they should really keep in the set list are OSC, ITE, Papercut, Faint, and Bleed It Out. Other than that, I would love to see new songs and never heard songs played during their set list.
Fuck that... They have WAY too many huge singles to do that. And tons of albums, tons of eras of fans, etc. Don't have to play each and every single, but the biggest ones from each album, for sure. No way that they wouldn't play Numb or What I've Done, both of those were hugely successful and are good songs that deserve to be played, even if you hate them as a hardcore fan. A lot of people enjoy those songs that aren't hardcore fans. What I've Done in particular has always sounded amazing to me live, even to this very day. I think they really nail that song live, even Chester, and the guitar solo that Brad does now is epic.
The Requiem (opener) When They Come For Me Blackout Wretches and Kings A Place For My Head Guilty All The Same
I made a comment in February but now that I have actually seen their setlist here is my new answer: Given Up, Rebellion, Blackout, and Final Masquerade. Give the set some more energy.
Those would all be good choices in terms of power and energy, Final Masquerade the standout, but I´d also like Valentine´s Day, Robot Boy, Until It´s Gone, A Line In The Sand and I´ll Be Gone.
