...spatial aspect of the song...
If I may get little techie here...
At one time, I used to watch music in additional to listening to music. This was way before music videos came upon the scene.
As a good electrical engineer, I had an oscilloscope.
I used to connect the oscilloscope (in x-y mode) to the secondary preamp outputs (left channel to the vertical, right channel to the horizontal), and watch the Lissajous figures produced by the music. (primer on Lissajous figures...

"spatial" resulted in a circle on the oscilloscope screen.
"not spatial" resulted in a line on the oscilloscope screen.
OK, with that in mind. Something that I noticed when playing a silent track (i.e., no music, just quiet) from a vinyl album and a CD...
The CD's Lissajous figure was minimal. Not much going on. A small circle in the center of the screen.
The vinyl's Lissajous figure was much larger. Not surprising, given the inherently louder background noise of the vinyl.
But the interesting aspect was that the vinyl's Lissajous was circular. Indicating that there was a lot of out-of-phase information in the background noise of a vinyl album. And a significant majority of that out-of-phase background noise was very low frequency (i.e., less than 15Hz.)
That led me to wonder, was some of the "spaciousness" sound that has been attributed to vinyl a result of that out-of-phase low frequency background noise that seems to be inherent in vinyl?
Oscilloscopes are cool.
