Kudos also to Mr. Daughters for the Drive-By Truckers reference in his profile...
To take the analogy further, it might make more sense to compare the flow of a golf course to that of an album of songs, rather than one song on its own. The opening tune should grab your attention and give you an idea for the theme of what's to come without giving too much away, and then take you in all kinds of side directions with variations in rhythm, melody, and length.
I'd hate to get away from Neil Young, but if you want to get into true geekhood about it, consider the flow of "Abbey Road." "Come Together" prepares you for something completely different, then it opens up with "Something," alternates between cutesiness and rock for awhile, shows some true beauty around the middle, and then culminates in a brilliant medley that reaches a dramatic and reflective conclusion in "The End." There are certainly courses that flow in a similar fashion, and I wonder if guys like Jim Engh who like to work while listening to certain music are ever influenced by that side of it.
If he's got an "Astral Weeks" out there, I'm all over it.
