Proper Motion from Star Stuff by Chris Harris
Stars that are close to the Solar System can be seen to move against the background stars as the Earth orbits the sun, thanks to parallax (the same phenomenon that you see when you hold a finger up at arm's length and look at it with first one eye closed, and then the other).
A star's proper motion is the motion that can still be seen when the effects of parallax are removed. And some stars near us are really shifting; Barnard's Star is heading in our general direction at around 110 kilometres a second!

Lyrics
Relative directions
in matters of the heart
Despite a common background
we slowly drift apart
By day we cannot see the guiding stars we need
At night they show where our trajectories will lead
It's more than parallax
Viewed from eye to eye
Your proper motion
is revealed as we pass by
From our own perspective
We see the other move
But which of us is static
is difficult to prove
Close enough as neighbours
Occupying space
From just part of the landscape
To gone without a trace

I'm still trying to get the music I record to sound like the version I can hear in my head. To do this I've ended up playing every instrument I can get my hands on. These days, I'm closer to "That Sound" than I used to be, but the journey continues.
