Unfortunately it's a bit of a catch 22 IMO:

If everybody recognised it and loved it as much as all of us die-hards on here, they'd play it more often and it would take away some of the 'wow' factor when you do actually get to hear this epic masterpiece.

On the other hand, when most people don't react to it as much, it gets played less and you feel truly priveleged when it does make an appearance.

It's a travesty that it's not appreciated by more fans I agree but there is the "up side" of that special feeling when you do get to witness it.
