Spectrum analyser

I have found something interesting.

Play the beginning of both of the first tracks of these (on tidal) :-

Stereo Check
by
Bunker Analog

and

Studio Monitor Placement
by
Baixa Fide lidade

See if the spectrum analyser shows any frequency activity when the signal plays through the Right hand channel only!
It seems as though only the left channel contributes and not the sum of Left AND Right.
