I think with stuff like "what the best songs are" its very debatable especially with a requests show. First off, not everyone who buys the ticket will vote so imagine if your going wanting the classics and end up with St Anger in its entirety or the vast majority are songs from after the first 5 Metallica albums. Second, everyone has different taste i personally dont want to hear what a lot of people want just because its never been played before. I mean il put this in a Maiden situation, i wouldnt want a setlist with The Educated Fool, Como Estais Amigo, The Edge of Darkness, 2 AM, The Unbeliever, Weekend Warrior, The Apparation, Strange World, Purgatory, Twilight Zone, Fates Warning, Mother Russia all in one setlist just because theyve never been played before. Yeah one or two would be cool but a whole setlist made up of it? No. Itd get boring easily. A whole setlist made up of songs metallica have never played in my eyes (i have seen Tallica 3 times, have all tallica albums) would be horrible, put 2/3 in then fine theres still 14 other songs to wow the crowd with would be more entertaining.
