What’s in a melody?

We’ll keep it short and sweet.  About twenty minutes ago, I was just sitting in front of the television when a Reese’s commercial came on.  As its music, it used the opening strains of Gustav Holst’s “Jupiter, Bringer of Jollity” from The Planets.  This is without a doubt my favorite piece in all of classical music, if only for the gorgeous middle section.  It should be semi-familiar to even the uninitiated, but if you need your memory refreshed, here’s the section in question:

Some things just cannot be expressed in words.  The beauty of this piece of music is one of those things.  It has been my favorite melody for as long as I can remember.  To me, it is the symbol of hope before that word got trademarked by political campaigns.  It is timeless, ageless, and peerless.  It’s the sort of melody I hope to write someday.  A hundred years from now when the majority of modern artists are all but forgotten, people will still be playing this piece of music and gaining inspiration from it.  There are no words (though the British tried to lyricize it).  It needs no words.  It speaks in a language all who truly listen can understand.

Anybody else have a piece of music (no matter what kind) with which he or she has forged such a connection?
