Honestly, part of the appeal of songs like Disposable Heroes is that they aren't set regulars and I honestly think if they were to make Disposable Heroes a set staple it'd lose its lustre and just become boring after a while. We're seeing that with older metallica songs that are played all the time e.g. Blackened, Creeping Death, Seek & Destroy, etc.
Yea Blackened never gets boring either if you ask me. Disposable Heroes certainly wouldn't. The Four Horsemen is played quite often and I don't think that one bores people when they play it. So I can't agree with your comment..at all.
