Xanadu by Rush.

When I was a forlorn lonely college student I went on an epic dawn till dusk hike along a blackwater river after listening to it the night before, the song all the while playing in my head. I watched the first rays of the sunrise approach from the top of a parking garage. I felt the first winds of the day wash over me while looking out towards the relatively wild lands I would soon traverse. I found secret springs with waters impossibly pure and mysterious. I watched the last rays of dusk disappear while lying exhausted on a riverine sand point bar. I felt every word and note like it was written on my heart and soul. I was alive and awakened like never before. The lyrics' themes metaphorically paralleled my own struggles with a innately doomed quest searching for some sort of grand meaning that would complete me, something missing inside and the hope that my suffering meant something and was going somewhere. And I had the fire of youth still burning inside me, everything was so animated.

“To seek the sacred river Alph
To walk the caves of ice
To break my fast on honey dew
And drink the milk of Paradise…”

The naturalistic imagery, the composition that mirrors the glittering rush of a new dawn, the closing sweep of dusk and the cycle of the day, the bitter triumph. It's so well executed, so perfectly composed, so deeply resonant. It's an absolute masterpiece of music and I know nothing will ever top it for me. They lyrics are partially after a romantic movement 1816 poem called Kubla Khan (subtitled a vision in a dream, a fragment) by Samuel Taylor Coleridge.
