To argue the other side...

...of the post I wrote on my other blog today, I'll admit that "Because It's There," a guitar instrumental by Michael Hedges, is an appropriate theme for climbing a mountain.  It conveys the drama, scale,  and uncertainty of such an undertaking.  The gripping tenseness of its recurring theme fits the endurance one has to have and the leap of faith one has to take when climbing.  It would also work as an accompaniment for a film about a plant's life cycle.
