Because they feel that the average fan wants to hear Numb, In The End and What I've Done. In other words - the hits. Maybe not more than 20% of the crowd at a concert are hardcore fans like us. When an average fan hears Forgotten or QWERTY, he'll be like 'Wtf, I've never heard that, is that LP?!' At least that's what the band say. It's stupid IMO, I want a lot of old songs to be played live, but it doesn't look is if it's going to happen. At least bring back With You or Figure - fan favorites. With You rocked as an opener in the past, and I think it's quite well-known, despite the fact it has never been a single.
