To me, the song represents the years wasted on hunting for something "meaningful". But so many years without success brought us to the point where we cannot realize we got it.
"Beyond the hill
A distant song
But that hill
Keeps going on and on"
represent something that we are "working" for to get it, but goalpost moves all the time.
And as time moves on, we get colder and colder to everything that surrounds us.
