Wanted to say the same. The voting would hugely depend on what's for vote. I'd doubt it would even include EP stuff for example.
Just look at Metallica and their Request tour, most of the shows had the usual stuff voted by fans, only a few had some rarities. We'd have to work together to get something special voted for LP. Casual fans are the big majority and they want to see the classics aka the singles, so many people don't even know Easier To Run or And One, so they'd never even vote for them. If people for example had to vote between 2 songs, the single would always win.
People go crazy for Numb, Crawling, In The End, One Step Closer etc. and the band knows that. They are in a very difficult situation having so many singles. We've seen people on Carnivores whose world would have literally ended if they didn't play Crawling...
